Windows RAID 0 question performance question

Question: Windows RAID 0 question performance question

Hi folks / performance gurus

Got an old server 4 HDD storage bays and SSD with Raid 0 -- created 2 arrays of 2 logical HDD's but 4 physical HDD's (1 array 2 X 4TB, 1 array 2 X 3TB) --

Is this better than creating 1 array of all 4 HDD's - I'd lose some space because the arrays have to be the same size.

I'm not too bothered on other issues of RAID 0 -- I want the fastest HDD SPEED I can get out of the system - I've plenty of backups so HDD failure here isn't a primary concern.

SSD is the boot device - works fine -- just need info on setting up these 4 HDD's for the best performnce -- Storage array is set up in BIOS before Windows boots.

Help here appreciated -- I can usually get stuff to work (old Engineer) but don't necessarily have the knowledge to optimize performance.

Cheers

Preferred Solution: Windows RAID 0 question performance question

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Windows RAID 0 question performance question

What do you need the array speed for if you have an SSD as a boot up drive? If it's just for storage, raid 0 is like putting all your eggs in 1 basket..I know you have backups but having those drives independent of each other will give you less chances of a failure and headache.

I have two option for setting up my new HDD array. Would it be faster to have:A single WD Raptor (10k rpm, 8MB Cache etc) for my OS. Then a large 200GB+ SATA HDD for everything else; games, programs etc. Western Digital Raptor 36.7GB SATA150 (10,000rpm, 8MB Cache) + 200Gb Seagate Barracuda SATA150 (7,200rpm, 8MB Cache).

OR
A RAID -0 using 2x WD Raptors for all my information, OS, games etc. 2x Western Digital Raptor 36.7GB SATA150 (10,000rpm, 8MB Cache).

I have recently installed Win7 to my old WinXP system, and I ran the Windows Experience Index tool on my system. All of the rankings were 7.0 to 7.2, except for the Data Transfer Rate which is 5.9. The pertinent equipment in my system is as follows:

ASUS M3A32-MVP mobo
AMD Phenom 9600 quad core CPU
4GB Corsair DDR2-1000 RAM
2 Western Digital Velociraptor 10,000 rpm HDD's

The concern I have is that even though these are not the newest top of the line hardware, I have always been under the understanding that with my hard drives set to RAID 0, and with them having the higher RPM rating, that the data transfer rate would be on the high end of the index. 5.9 on the index seems too low in comparison to the rest of my hardware.

The ultimate question is, could it be possible that a RAID 0 configuration may actually be working slower than if I were utilizing one of the hard drives as a stand alone drive without a RAID 0 configuration? Thoughts/tweaks/etc.... Thanks.

I have an MSI K8N Neo4/SLI Platinum motherboard with the onboard serial raid. I have downloaded the NV Raid drivers from MSI's web site and pressed F8 to install those drivers when I start the Windows install.

I have 2 WD 36 gig Raptor hd's in a Raid 0 configuration for a total of 72 gig raid partition, this is my C: drive.. I also have a D: drive that is a 200 gig hd and an E: drive that is a 160 gig hd.

Now the problem...when I get to the screen in the Windows installation process where it ask what partition and drive to install Windows on...it only shows my 200 gig hd (as my C: drive) and my 160 gig hd (as my D: drive). It doesn't show my raided drives.

Any suggestions on what I'm doing wrong here?

When I boot up it shows my raid is there in the bios start up screen.
 

Answer:Windows XP 64 bit install & raid question

First off its F6, are you hitting F6 or F8?
Are you sure you have the drives in the NVraid ports or is there another chipset for raid on the mobo?

check connections, power, and test different cables if you can.

I know that XP is a bit different than '98 but when I bring up the task manager and go to the "performance" tab I really don't understand what everything means. Physical Memory, Kernal Memory, Comitt, Page File.... can someone give me a little lesson in how to interpret my performance?

My system has 128mb RAM. That said, here is what my performance reads now:

Physical.........129580k
available..........64204k
system cache...72216k

kernal...............31756k
paged...............27252k
nonpaged...........4505k

Page File usage: 126mb

total: handles, 5282
threads, 298
processes, 25

Commit Charge:
total............129584K
limit.............380536k
peak............185404k

Is this good? How do I use this info to determine how well my computer is performing? Why is Physical and Commit slightly different?
 

Answer:Windows Performance Tab Question

For a detailed description of what they are, open up the task manager and click on help, under the contents go to performance fields overview. They have pretty good explanations of what they are.
Without knowing what you use the computer for, I would say those are pretty good for things like surfing, light gaming, email and such.

Hello,

I recently did the upgrade and update to windows 10 pro. I am happy with it and all is OK. What I am wondering, Is I need to do a clean install. So, I currently have a raid set up on it and I did not set it up. The great thing is the upgrade/update kept all my settings and worked well. Even kept my raid.

If I do the clean install, will I loose the raid drives. I know the install only effects the C drive. But these other drives where i have backed up things to. Will it carry over to my fresh install of windows 10?

So, if windows 10 installs and all is OK. But no raid drives. How do I bring the raid drives back on. Is there a way I can do this with out loosing it during the fresh clean install?

Thanks, Karl

Hi there. Am running the above board in my system and am using both IDE1 and 2 for 2 hard-drives and a CDRW and DVD drive respectively. I am wanting to plug another couple of hard drives into my system and have read the manuals for the motherboard but still can't determine if IDE3 and IDE 4 (reserved for RAID functions) are able to be used as additional normal IDE connectors meaning I can have upto 8 IDE devices in my system.Does anyone else have this kind of board and how are you using the extra IDE3 and 4 terminals? Does anyone know if they can be just used for normal IDE devices? I don't really want to replace any HDD's as I already have a 40 and 60Gb unit in the machine but the drive's are filling up!Thanks!

hello everyone,

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,
 

Answer:RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

Answer:Tecra 8000: Question about the Windows XP performance

Hi Paul, i have recently reburbished a Tecra8000 (192 RAM + 288 MHz + 14GB) which has a much lower specs than urs. i was planning to just put Win98 on it but because it lost the original Toshiba system files n the DVD drive was unable to play DVDs. The user was a novice n it'd b difficult for her to have to install drivers every time she has a new device. i therefore took the chance n installed XP pro for her after reformatting. i then got her a wireless mouse n signed her up broadband n MSN messenger etc. she was v impressed with the performance and the internet connection etc. so far so good. she told me she even managed to get a new printer working without any help!

the only thing is if u rebuild the system from scratch, u have to prepare not having the original Toshiba system files. i definitely had to re-install the monitor driver in Win98. (the screen would look awful otherwise.)

Good Luck!

In our server room we have a HP DL360 G5 that has some drive mirroring going on. 4 of the drives are utilizing RAID 1+0 where two drives are seen as a single drive and than mirrored to the other two drives, which are also seen as a single drive. I need to increase the capacity of those drives and I've found that I can replace each one, one at a time, with larger capacity drives and this will work. I don't have to break any mirrors, make any configuration changes, etc. However, what I don't know is how long to wait for each drive to complete the mirroring process.

In other words, say drives 1-2 are one set and 3-4 are another set. Now let's say I replace drive no. 4 with a larger drive. It will take time for that new larger drive to go through the process of being completely merged with drive 3. Does anyone know how I'll know when that's done so I can then continue on and replace drive 3 with a larger capacity drive, followed by each of the other drives after that?

I have a 250GB Samsung 850 EVO that I put in my personal laptop back in May. I also have a 250GB Samsung 850 EVO that I just put in my desktop a couple weeks ago. I'm thinking about wiping both, and using both in my desktop for a RAID 0 configuration since I don't use my laptop at school anymore (I had only put an SSD in it for faster load times so I could make sure I was up and running fast enough to take notes).

My question is this: is it safe to use two used and differently aged (albeit identical) SSDs of different ages to run a RAID 0 configuration, or is it necessary to use two new identical SSDs? Do you think I'll run into stability and reliability issues?

My mobod will support many different types of raid so that is not a problem. My question is about raid and the os. What would be the best way to do it. I don't want any other type of raid so don't go there. Any way should I put the os on a whole seperate drive and raid the the other two drives or should I partition the drive and do it that way? Any advice? Thanks.
 

Answer:Question on raid 1?

I don't see the point in partitioning, it won't do much to help.
Raid 1 = mirroring, so i'd use the other 2 drives as you said and raid them together, assuming your onboard controller lets you do that.
Bear in mind that you will then only have data redundancy and not system files.
Someone might come along shortly and explain a better way to mirror just 2 drives together, although you may find its more straightforward than you first thought.

Question: RAID question

I have a system with one Maxtor SATA disk of 80 GB. I'm running Win XP Pro. I would like to add a second identical disk, and configure RAID 1, mirroring. The question is, how is it done, and can it be done without reinstalling the whole system? The mainbord is a A7V880. Thx in advance for the response.

Answer:RAID question

Depend on your OS, you can only setup RAID on 2000, Server and XP Pro, but you have to convert both harddrive to dynamic in adminstrator tools/computer management/disk management.

It's usually done via software, your motherboard should provide you with one. Connect the second harddrive (make sure they are identical, same size same brand) to the secondary sata connector and whatever software you will use follow the instruction on how to set up mirroring.

You don't have to reinstall your OS, it's just like adding a new hardware.



You can not go back to basic if you are in dynamic.

Thanks for your time!

Answer:Raid Question

To create RAID you need to format the drives. The RAID controller will do this. Therefore what drive letters you have now are irrelevant. I strongly recommend against using different drives in a RAID setup. It can cause problems. With the hardware you have now, I do not think RAID is the best choice, however when you buy equipment in the future, considering the use of RAID then would be a good idea.

Answer:Question Re RAID 0

I have 2 harddrives in raid 0

If you are running 2 or more, and take 2 away, you will break your array and they will not boot up. If you take them out the data will still be there, as long as you dont change them, and after testing the drive itself you can reinstall it back into your RAID 0 config and boot. If you change your array you will break the array and will not be able to boot as this will wipe out the array of the installed HDD's.

If you want to change the array, and still retain your RAID 0 array data, image your RAID 0 array, then reset your array to RAID 0, and then reinstall your disk image. The array will be intact.
Here is free software to image your array: http://www.paragon-software.com/home/db-express/

To get the most out of your hard drives it is recommended that you use different ports for each hard drive.

Maybe you could use 2x Raptors on your SATA RAID, and get a mass storage device as ATA (PATA)?

First some background: A dude brings me his PC 'cuz it's not powering up. The PSU tested "dead" so I swapped it for a brand new unit. Now, after the PSU has been completely connected to the MB, HDDs, CDs, etc, and the power is plugged in to the PSU, as soon as the main switch on the PSU is turned on, the PC powers on, the fans spin, etc, without needing to press the power button on the case, but there's no "BEEP" and no video. After much diagnosing and part swapping, it is discovered the MB has failed also (which I had assumed right when it powered on w/o requiring the use of the power button on the case). He was running a RAID1 (mirrored) on drive(s) C: using the MB SATA connectors (it was two 250gb SATA drives being cloned in real-time; Windows sees it as a single 250gb drive; but you knew that already) and he was running Server 2003 Std. So I swapped the mobo, performed a repair install of Server2003 on a single drive from his mirrored RAID (on drive C: ) and that went perfectly fine (I left the 2nd drive from the mirrored RAID alone just in case something went wrong). I installed the drivers for the new MB, and all is well. It is at this point that I am told "out of the blue" that he's running RAID5 on the other 3 drives that were previously connected to an Adaptec AAR-1420SA card.

Answer:Question about RAID(5)

You might check further on this to be exactly correct, but RAID5 needs 4 HDs to run correctly. I'm not an expert, but running it with 3 drives will get some flakiness if it runs at all. The info I read about RAID stated that in any config, the hard drives need to be even. 2,4,6,8 as the RAID array goes up in number.

Question: RAID question

I have a 74gb raptor right now. if I get another HD does it have to be the same size to run a RAID0 setup?
 

Answer:RAID question

A RAID 0 can be created with disks of differing sizes, but the storage space added to the array by each disk is limited to the size of the smallest disk. For example, if a 120 GB disk is striped together with a 100 GB disk, the size of the array will be 200 GB.

Question: RAID 0 question

I have a question about my setup and RAID 0 speeds and hard drive speeds in general. I don't seem to be getting what I should out of my setup.

I recently setup a computer with an Adaptec 1200a RAID card and configured a RAID 0 array. Installed Windows XP Pro and benchmarked it with SiSoft.

System Specs:
Intel D865PERL MB
Pentium 4 2.8 800mhz bus 1mb cache
2 x 512mb Crucial PC-3200 Dual Channel
2 x 120GB WD Special Edition HD (8mb cache)
Adaptec 1200a ATA RAID card / RAID0

It averaged 65mbs. Wow, pretty good I thought!

I decided to put a RAID system in my home computer.... I went for an Adaptec 2400a ATA RAID card (has 32mb cache) and setup RAID 0 - two of the same HDs. My System Specs:
Epox 8RDA+ MB
Athlon XP 2800+
2 x 256mb GEIL PC-3200 Dual Channel
2 x 120GB WD Special Edition HS (8mb cache)
Adaptec 2400a ATA RAID Card / RAID0

I ran the same SiSoft benchmark and got a result of 41mbs not too good.

I also have a Western Digital 180GB Special Edition and a Western Digital 200GB Special Edition in my system. Curious, I benchmarked those:

(Both are master drives on their own channels.)

WD 180GB (IDE0): 29mbs
WD 200GB (IDE1): 43mbs

I am totally stumped. I don't know where to go from here. I was expecting at least 60mbs with the RAID and now I'm finding out that my 200GB drive is actually the fastest. I also have NO idea why the difference between the WD180 and the WD200.

Hey all,

I have set up a RAID array on my computer. I have 2 IBM 40 gig drives running in RAID 0, they are both on separate channels, IE, one is primary on ide 3 (raid channel) and one on ide 4 (raid channel), My question is, I also have another 40 gig drive that has all my windows and stuff on it as it was BEFORE I set up the other drives as raid. Now can I put them on the cable as the secondary slave on either ide 3 or 4, or should I put it on another channel alltogether, like with my CD-RW ? Does it matter ??
 

Answer:Different RAID question

Plugging your other drive into another IDE channel altogether is no problem. I don't know for sure, but you should be able to plug it in as a slave drive also, but I wouldn't recommend it if you have an extra IDE channel open because slave drives are slower than primary drives.

I have a similar setup, but with 60GB hard drives and have had no problems installing extra hard drives. Hope this helps, post back if you have other questions

No, the mirror will be broken, re-attaching the hard drive and rebuilding the mirror would overwrite the data on the external hard drive with the contents of the internal hard drive.

i have 2, 160 gig Western Digital Ultra 100 HDD.......i want to run the RAID that my mobo offers. Its a ASUS P4P800 Deluxe with 800 FSB.

Here lies the question: since XP will not notice any HDD over 137.4 gig, should i install the "Promise Ultra 100 TX2" that came with the HDD ( its a PCI card ) that will allow the OS to notice it as a 160 gig HDD? And by doing this i would have to hook up my HDD's to the card, thus not hooking up to the RAID IDE prim.1 on the mobo.

By connecting to the controller card, will that allow the raid to still work? Dumb question but i cant get it to work by just connecting to the Prim. 1 on the RAID of the mother board.......and yes i went in and set up the array and set up the RAID as RAID-0........

thanks ahead of time for all help.............

Answer:RAID question..

Ok, here is the real limit information.
http://www.microsoft.com/technet/tre...c_fil_dwwu.asp
I think you have an issue with drivers that is limiting you to see the disks. Also, due to these being created without formating, you will want create the drive partitions in diskmanagement.
The second raid controller will not disable the onboard, and should not cause you any trouble. Make sure the drivers are installed and then create the partitions on the volumes.
This should fix your problem.
Good Luck

Hi,

I am thinking of buying MSI G Series GT780DXR-405US Notebook which comes with 2 HDD 500GB in RAID. I am assuming RAID 0 because the specs do not say explicitly whether RAID 0 or 1 or.....

Here are my questions :

1) Can I disable RAID (if yes, how?) and replace one of the 500GB HDD with 250GB SSD ? I do NOT mind sacrificing the performance gain offered by RAID 0 by doing so. I feel, I will gain some by replacing one of the HDD with SSD.

2) After I do step 1) can I boot it off 250 SSD and how can it be done assuming I am NOT getting any recovery disk with the laptop?

3)Are these 2 steps too complicated ? If yes, shall I look for another laptop with 2 hard disks in NON RAID formation?

Question: RAID 1 question

Hi,

I'm planning on getting a PCI to ATA RAID card so I can run a pair of WD 250GB drives in a RAID 1 configuration (mirrored). These drives will be for file storage only. My OS (Win2K) and applications will be on a separate drive connected to the mobo's onboard IDE (Primary Master).

When the mirrored WD drives are full, I plan to replace them with a fresh pair of drives. So my question: can I install just one of the full WD drives in an external firewire case for read access? Or will the drives need to be paired in the RAID 1 configuration for readability?

Is it possible to eliminate the Raid-1 so that I can just use the 2nd hard drive as a continuation of the first so that the computer can have twice the capacity than it does now? Apreciate any advice. Thanks!
 

Answer:Raid-1 question

Yes. Make an image of your system using something like acronis.

Now boot into the raid bios and delete the raid array. This will restore both drives to non-raid status.

If this is an onboard type of raid controller, you will need to restart and enter the system bios. Set it for non-raid or standard ide. Save settings and exit. Note if you use a real raid card like a highpoint or promise card, this would not be necessary.

Now boot with your acronis boot cd and restore the image. You will need to partition and format the other drive in order to use it.

Note if you do not have acronis, you can do the same thing by reinstalling your system and all apps. This would of course take longer.

Is the RAID configured thru your motherboard bios or is it a Windows Software configured RAID? If motherboard configured, what is the make/model # of motherboard?I had a similar SMART failure like you describe that doesnt show all the time and it was with 2 500GB Maxtor SATA drives that I was using also as RAID 1. Because I was running RAID 1 as exact mirror I ended up just running them until the one that failed died for good... such as it wouldnt spin up. In the end I found out that the early Maxtor 500GB SATA drives ran hot even idling, and the problem was that sandwiched together in the case there was a heat build up and that was the cause for the SMART failures which lead to the 1 of 2 drives crashing. I also would hear strange noises coming from my tower a day or so before that 1 drive died for good. Sounded like a metallic ping noise, which when I opened the case was coming from one of the 2 at the time that I wasnt able to distinguish. When that drive died it was burning hot as well as the other same drive next to it. Felt like you could roast an egg on it. Ended up decomissioning this 500GB drive as a vital drive and retired it to occasional external drive usage for moving large files between systems. And with the 500GB that roasted, Maxtor's warranty expired on it, but when Seagate bought out Maxtor, Seagates warranty then applied to Maxtor products with longer replacement warranty and so I shipped it back for a brand new Seagate Refurb 500GB that is almost 1/2 ...

Question: RAID Question

Hello,

So I am hoping to run two hard drives as striped RAID (0) and have a third to manually back any the important information / files.

If I were to use windows backup to back-up all of my files/desktop/etc onto the 1TB hard drive. Then reformat the 250's and run them as RAID 0 with a fresh XP install. Would I be able to copy back the backed-up files into the fresh XP install and have everything as it was before or is this not even a possibility?

Question: RAID Question

Does having a RAID configuration only work with 2 or more hards drives on seperate SATA ports?

For instance, could you partition a hard drive and then use a RAID configuration on the two partitions?

Answer:RAID Question

That doesn't make any sense. What wud u gain by doing this? Let me tell you why. Even if this is possible with a s/w Raid controller, it server no practical purpose.

Raid 0 - improves performance by allowing multiple HDDs to participate in the IO process. When one is working away to find info, the other one can get new requests, etc.

If you have both "hard drives" in one physical hard drive, Raid 0 is pointless as there is only "one" HDD and the improvement of multiple HDDs participating in IO is not present.

Raid 1-whatever - this is used for redundancy. If one disk fails, you can recover data. If you have your "raid HDDs" in one physical drive, where is the redundancy? If the drive fails, the data is lost!!

Answer:RAID 1 question

From Wilkipedia; "Raid 1 without parity. Provides fault tolerance from disk errors and single disk failure. Increased read performance occurs when using a multi-threaded operating system that supports split seeks, very small performance reduction when writing. Array continues to operate so long as at least one drive is functioning."If one drive goes belly up the data will still function. Once you replace the faulty drive check your raid software to ensure that the new drive catches up with the raid, depending on the size of the drives and amount of data it may take a little while.Hope this helps.

Hi,

I assume you are referring to a RAID0?

For user data (music, photot's etc.) that shouldn't be a problem. For installed programs and their associated files, I'm not sure it would work.

An alternative option might be to image the existing system using something like Macrium, then build your RAID, and then attempt to restore the Macrium image to the new RAID system. However, I forsee some problems with the registry entires.......perhaps someone more experienced could comment?

The safest bet is probably to perform a reinstallation once the RAID is built.

First, the name alone is a hint: Redundant Array of Inexpensive Disks.

Raid 0 is Stripped and Raid 1 is Mirrors.

Stripping is a performance choice to allow data transfer on one HD while the
arm/head is seeking a new location on another.

Mirrors is a Fault Tolerance choice to keep the system running when one HD
fails. NOTICE: Fault Tolerance is not the same as BACKUP!

Now as to your question; Fault Tolerance is a physical issue of the device and
not a logical issue on partitions. While you could RAID-1 one drive to its mirror (ie a 2nd hd),
multiple partitions on it complicates your recovery. It would require TWO
backups to be synchronized in time (one/partition) to effect a meaningful
recovery from failure.

From the looks of it your BIOS has RAID support. The display shows that you have no raid volumes defined and the BIOS found 2 SATA hard drives. If you want to setup a raid volume, press CTL-I. NOTE: if you elect to setup a raid volume, all data on both drives will be gone. I would just ignore it.

Question: Raid Question

Hi all, I wasn't sure where to put this topic so I put it under here.

What I'm trying to find out is there really a "big" performance difference with Raid 0 (striping) verses Raid 1 (mirroring)? I have two 250GB HDs and I'm trying to weigh the pros and cons of which way to go.

I appreciate any feedback.

Regards
Larman :bounce:
 

Answer:Raid Question

Hello, welcome to Techspot!

Raid 0 will increase the hard drive speed overall, and give you the equivalent capacity of both drives (500gb). The con of raid 0 is that if one drive goes bad, neither will work, as they are made to be one logical unit. So it doubles the rate of failure compared to having one drive(you have two drives that could fail in raid 0 vs 1 drive if you just have one drive).

Raid 1 will give you the storage of 1 drive(250gb), and each drive will be a copy of the other drive. It is no faster than a single drive, but it gives you a backup hd if one goes bad.

Question: RAID 1 Question

Hello.

I?ve been having a terrible time with my computer going through periods of horrible sluggishness and even freezing up for 15-20 seconds. It never crashes, just gums up or freezes then goes back to normal after a while. I?ve tried malware and spyware removal, but to no avail. The CPU temp is fine and the task manager (and process explorer) shows no applications of processes taking up resources while the problems are happening.

I?m thinking (because I can't think of anything else) that it might have something to do with the onboard (nVidia) RAID 1 I?ve got going on. My question is: can I just unplug one of the drives and boot up the other one? I?m thinking if the RAID is giving me problems, the one drive should be fine alone. However, if it?s some corrupt Windows files, I can just format the one drive, and when it?s up and running, pull the file I need (family pictures and videos) from the other drive.

What do you all think? Am I missing something? Does this sound like a good plan?

Thanks in advance for your help!
Tom
 

Answer:RAID 1 Question

If you unplug one of the drives in a RAID 1 (mirrored) array, the PC will still boot. The catch is that, when you reconnect the other drive, the RAID will immediately kick in and re-mirror the drive (a full copying of the disk, not an incremental backup - very time consuming).

Check the manufacturer's website (Western Digital, Seagate, etc.) support and downloads section to see if firmware upgrades are available for your drives. Both WD and Seagate have had recent issues where - if a firmware update isn't installed - there is a significant risk of RAID issues and/or drive failure.

Also, check the motherboard mfr's support/download section for any RAID software updates.

Hope this helps.

Question: RAID Question...

Hey,

I'm going to be installing a RAID 0 array in my system soon and I came across a potential problem: I only have six SATA ports and four of them can be configured into RAID. The issue here is I'm only going to use two hard drives for said RAID. I have five other drives to consider, two extra hard drives, two laptop hard drives, and a DVD burner. If I take four SATA ports away, I can only have two other drives running, which is a problem.

I'm kind of thinking is it possible to put a DVD drive in a SATA RAID? And, can I use the extra remaining SATA RAID port to perhaps use for a laptop drive without it being in part of the RAID 0? I'm slightly lost here....

Hello geeks

I need your help with this ! I'm willing to purchase a PCI RAID controler to ( Merge ) between my two ATA hard Drivers physically .

what I need to know is, do I need to care about the mother board type ? will all motherboards supported ? as long as it's a PCI card.

the configurations which I need to do after installing the card will be only in the OS or on the BIOS to ?

Thanks

Answer:Question about the RAID

it depends on the RAID card. cheap RAID cards will be software based, similar to a software modem if you are familiar with them. that means not all have all the hardware controllers necessary to make them work (this makes them cheaper to make and buy) and part of the what is necessary to make them work is run as software by the operating system. if you get a completely hardware controller then you should be able to access it with a particular key during boot.

i'm not entirely certain what you mean by that. i hope you don't think that you can just merge the drives into a RAID. if there is already data on them you will either have to back it up or lose it. if you want to make a RAID 1 array and only one drive has data it is possible however given you need help i'm guessing you will be wanting a RAID 0 array as only people who already were familiar with RAID would have use for RAID 1 .

Question: Raid 1 Question

A friend of mine had raid (I am assuming raid 1) set up on his WindowsXP box, using Intel Matrix Storage. One of the drives died. He has a new drive. Do you just need to set the jumper on the new drive as a slave, and pop it in? Do I need to format the drive with the correct file system? Or, will it copy the file system to the new drive also? Do I need to activate the raid again? If you open the matrix storage program it does show that a drive is missing. I cannot have it copy the info from the blank drive to the drive that has all his info on it.
 

Answer:Raid 1 Question

Never mind, I found the info. Its here if anyone needs it:

Question: Raid 1 question

I have a proliant server with 2 hot swap scsi drives on raid 1.
Every week I take out drive # 2 and take it to another location and put in another drive in its place. So now I assume it writes the data from drive 1 to drive 2.

I use acronis and make a complete backup of all files from another computer to that raid 1 array on the proliant server. Now I want to pull a file from my hard drive that is currently not in use but has a backup from last week. Since acronis does a backup every night, the data currently stored on the 2 drives in the raid array is too new.

So now I want to know how to get the data off of the drive that is not in use.

Can I just shutdown the server & pull the 2 drives out that are in the server now and put in my 3rd drive from last weeks backup and restart the computer. Will I then be able to access that drive?

I ask because it seems like I tried that before and screwed up the array. I think I just re-setup the array with new drive and then I could access it?

Just looking for some tips so I don't screw up my backup.

thanks
-George

Question: Raid question.

I want to experiment with Raid, Is it possible to connect a older pc with 4 hard drives in it, to my computer, and use the old computer as a RAID?

If so, Is it worth the hasstle?

And if its worth the hasstle then how would I go about starting it?
 

Answer:Raid question.

I think you should take an interesting look here to get some idea. Using four disks you can take advantage of RAID 0+1 (stripe/mirror), RAID 1+0, among some others. If you can fit the physical space, you could get hardware RAID to connect right into your computer and let the hardware do the job for you. It might take nothing more than a PCI slot, two IDE ribbon cables, and the four drives to get things working. Otherwise you could connect it computer to computer, but you get a bottleneck in the speeds where the network is concerned. Is your network faster than the speeds of your hard drives?

Question: Raid Question

Lets say I have 2 WD raptor drives in RAID 0. If I get a 3rd hard drive used for multimedia storage could I put that in RAID 1 with the 2 Raptors?

So basically I would want it to be like this. All of the files (except OS and apps) that I save on the raptors would also be saved to the larger 3rd HD. But I would want files to be able to be put on the larger 3rd HD that would not go onto the raptors.

I hope I made that clear and is that possible?

Answer:Raid Question

im nota raid expert at all, and someone can correct me if im rong, but as far as i know, the answer is "No".

i read somewere b4.. i dont remember all the specifics, but it went like this.... i dont remember if it was just intelse new LGA bourds, or the LGA BTX's, but thy have a new matrix raid aray, that allows u to partition 2 equally sized HD's, and use half in Raid0, and the other half in Raid1.(example- both HD's split in half... section 1 from HD1 and HD2 is Raid0, section 2 from HD1 and HD2 is raid1)

thats the reason why i assume u cannot do what your asking with your mobo.

aight i got 2 quick questions about my raid 0 setup.

#1. What block size do u guys suggest? I'm deciding between 64kB or 32kB..................tell me what u guys suggest.

#2. I have two WD1200JB (8mB cache) hard drives in a raid 0 array and when i benchmark my drives in SiSoft Sandra, the result is almost the same or lower than an individual WD1200JB!!! I also noticed that the "buffered write" score was only about 15mb/sec when on a single drive it's about 40-45mb/sec!!! Can someone please help me out with this, because i have no idea what is going on...........

Thanks alot.........hope to hear from someone soon.
 

Answer:Raid 0 Question

What are you going to use the raid for?

A lot of very small files, a lot of larger files, or a mix of the two?

The block size setting depends on what you're going to use it for... If you're going for lots of (very) small files, 32kb will save you some diskspace, but if you're going for larger files (mp3's, divx's etc) you might be better off with a larger block size...

So until you tell us more, it's hard to help you out with what size to use...

I dunno about #2...

Question: Raid question

Mr./Ms. Moderator.....what about in my situation if your computer has two drives, are configured as Raid drives and you want your two drives back for storage? Any reply is appreciated........Will I have major problems if I change the RAID to "off" in the Bios?

Reba7
 

Answer:Raid question

I put this in it's own thread; replying to a guide is not going to get you much in the way of answers.

You cannot change the mode of the controller in the bios without causing problems. Almost always you with get a bsod with an error msg regarding hardware. The reason is that onboard controllers use a different driver depending on the mode selected ie raid, achi, standard ide. This is one of the many reasons I recommend a real raid card if someone wants to run raid. A quality raid card like promise, highpoint, etc does not have this problem.

You can delete the raid array in the bios and use your drives normally however you do understand that deleting the array destroys ALL data on the drive correct?

This means you will have to reinstall the os and other apps. There actually IS a possible way around a reinstall however it is somewhat complicated and requires acronis TI workstation and universal restore. This would allow you to make an image and then restore it to different hardware ie mode of controller.

Since this is a complex task, IMO you would be better off by doing the clean install.

Why do you want to get rid of the raid?

I remember researching this when I did my last build and if I recall raid 0 works best with matching drives. So I got two Raptors and set it up. Works flawlessly. WEI of 6.3 which seemed OK at the time. Then the SSD thing reared its head and I am now preparing to unplug the Raptors and just have a single SSD for the OS and a second mechaanical drive for data. It will hopefully be faster and simpler. I kind of wonder if Raid with mechanical drives is worth the effort anymore? Any thoughts?

Hi

Im considering installing Windows 7, well technically its still downloading from Microsoft but its getting there so while its going I was just curious how it performs on a RAID-0 system, right now I have 2x 500GB Seagate Drives at 7200rpm and was wondering if A) The increase is speed is definatly noticable and B) what the Vista rating is for having 2x 7200rpm Drives in there under Vista its a 5.9.

Also the RAID controller is hardware based and setup through BIOS on my P5Q-PRO, I didnt have to install the drivers so am I correct to assume the same on Windows 7

Thanks Guys

Hello,

I have two of these SSD's, and I have set them up in raid0 (with motherboard raid-mode setup as I dont have any raid controller).

My Windows 7 uses pretty long time to boot, especially with SSD's in raid.


What is causing this?

Answer:Windows 7 and SSD in raid performance

I can tell you that the boot process has a lot of variables...and the hard drives are just one. RAID with SSDs (especially just two disks) isn't really that useful, because you gain in some areas, but suffer in others that are key to Windows usage.

That being said, is the boot time really that important? How often are you rebooting? How does the system run once it is fully booted?

Hey all, just a couple quick questions.

I have 2 maxtor 120g (internal) SATA HDD's in a system that I am going to part out and sell in favor of using my laptop for everything.

These 2 drives are set up for RAID 0 and have WINXPPRO installed.

What I want to do is put these in an external enclosure to be used with my laptop. I found some that support RAID.

My question is: Will this be a plug & play operation or will I have to set up the RAID array again for the new enclosure? I dont want to lose my data.

Also: Do the parts exist to convert these drives to USB without an enclosure?

I was considering pulling the HDD rack out of old system and making it into a cooling unit for ALL my external drives.


Appreciate it!
 

Answer:Question about ext. HD enclosure w/ RAID

Before you dismantle your old system, move the data or save and restore the data to your laptop. You would very likely need to redo the RAID array in the new enclosure and that will kill the data on the drives.

I would think that you would want to protect the drives with an enclosure but there are converter cables that will convert IDE to USB without an enclosure.

Hi, I have WinXP installed already on a Raid 0 setup (2 80gb sata drives) with a 64k stripe..I'd like to experiment a little and try a 16k stripe..now when I go to reinstall windows again will XP format BOTH drives or do I have to do that manually? Thank you

Answer:Raid 0 setup question

Windows will do it automatically, but you need your MoBo specific raid drivers on a floppy disc.
You can find theses raid drivers on your MoBo's website if you don't already have them.
Then when you boot from the xp cd and setup begins, @ the bottom of the screen it will prompt you to hit F6 to install 3rd party raid or scsi drivers, or somthing to that effect,
hit F6, then make sure your raid floppy is in your drive, then when prompted, hit "S" and then enter.
This is a neccessary step, once you do this windows will treat your 2 80gb drives as 1 160gb drive.
Then when it asks you to hit enter to install xp, hit enter, then it will tell you there is already crap on the drive and ask if you wish to format.
From there its all automated.
By the way this is xp pro, if you have xp home it may vary a little.
