Raid0

post #1 of 14
Thread Starter 
Okay, I managed to pick up another 74G Raptor off ebay for $35 bucks, so I figured why not for cheap and Ive always want to try out a RAID0.

Ive been doing research on it and just want some advice.

What size strip should I use for 2x 74g drives? 128 Im guessing right?

I have only my OS installed on my current Raptor with all my drivers(vid/audio/modo..etc.), everything else is on my 640gb(apps/games/pics/media..etc) drive. Do I have to whipe my OS drive before I try to make the array?

Because I have Vista x64, I can load the raid drivers through my USB drive right? Because I dont have a floppy drive. And Im sure lastest raid drivers I would get on the ASUS site.

Should I uninstall programs off my 640gb drive? And reinstall them after I make the array? Because they wont work right if I reinstalled windows on the new array right?

Anything else? Any helpful tips? Ive read a few articles on making an array so I think I should be able to do it easy, its just that they were all kinda old. Thanks..

you would have to wipe that current raptor

when I was doing my raid with vista, I didn't need any drivers

I think you should re install them but I'm not sure

I would first play about with the stripe size. AFAIK a large stripe size is mostly for gaming and a small stripe size will be for speeding up the OS. Though a small stripe size can actually decrease performance in gaming I think
Meh...

That's fine.

I have only my OS installed on my current Raptor with all my drivers(vid/audio/modo..etc.), everything else is on my 640gb(apps/games/pics/media..etc) drive. Do I have to whipe my OS drive before I try to make the array?
Yes. Create array, format array, install OS.

Because I have Vista x64, I can load the raid drivers through my USB drive right? Because I dont have a floppy drive. And Im sure lastest raid drivers I would get on the ASUS site.
Yes, Vista supports floppy, USB, and CD/DVD.

Should I uninstall programs off my 640gb drive? And reinstall them after I make the array? Because they wont work right if I reinstalled windows on the new array right?
What programs are installed on yoru 640GB drive? Isn't everything installed on the other Raptor?

In red.
Once again...

When you create the RAID array, you will be prompted to continue as it will wipe all data anyway.

Any applications you have installed on the 640GB won't work on your new install because they would have had registry settings stored on the windows installation. These will need to wiped off the drive once you have your new installation up and running.

So:

1. Backup any important data.

2. Restart and go into BIOS, in there (Probably under intergrated peripherals) you should see a RAID option. Enable it and enable it again on the two SATA ports which you have the raptors connected to.

3. Save and exit BIOS.

4. Shortly after the POST screen, you should see an option like (Press F10 for RAID Utility). Press whatever it wants.

5. In here you want to select your two raptors for the array and make sure that the RAID mode is "Stripe" and "128k" is the stripe size.

6. Create the array and exit using the specified keys.

7. You are now ready to boot from the Vista disc and install.

Vista recognises Nvidia RAID arrays by default anyway, so you shouldn't have any issues during install. Once installed, you can go about installing everything again, including the 750i drivers off the Nvidia website found here: (These should be the first thing you install)

32bit: http://www.nvidia.com/object/nforce_vista_15.23.html
64bit: http://www.nvidia.com/object/nforce_vista64_15.23.html

I hope this helps.

Do you have write back enabled?

Find the array in device manager, right click > properties > Policies > Enable write cache.

Also, heres my 3 WD 640GB Caviar Blacks in RAID 0:



And yes your burst rate will go down when you use more and more drives on an onboard controller.
