Formatting and RAID0 M4s

post #1 of 13
Thread Starter 
So I have a current M4 128GB with Windows installed.

I have another and want to RAID0 them.

How do I go about formatting the SSD and then how do I RAID them up?

For format do this:
  1. Boot from the Windows 7 DVD/USB
  2. After booting you see the Install Windows 7 screen, press Shift + F10 to open a command prompt.
  3. At the command prompt, Type diskpart, press Enter
  4. Type lis dis, press Enter
  5. Type sel dis X (where X is the number your drive shows up as), press Enter
  6. Type cle, press Enter
  7. Type exi, press Enter

You drive will now be wiped.

Check out my guide to install Windows: http://www.overclock.net/t/1156654/seans-windows-7-install-optimization-guide-for-ssds-hdds

Do this first to make the RAID array.

How to: Set up RAID! Warning: Spoiler! (Click to show)
Set up RAID:
  1. In the UEFI/BIOS set the SATA mode to Raid mode
  2. Then when you restart your PC hit Ctrl+I (or Ctrl + G or whatever it is for your motherboard) after the splash screen appears when it shows a list of your SATA devices, it will take you to RAID setup menu
  3. Choose create a raid volume
  4. Give your raid volume a name
  5. Choose your raid type (Raid0 or Raid 1, or whatever you wanna do)
  6. Choose the SSDs/HDDs you wanna add to raid
  7. Choose your raid Block size (Default or 128KB is fine)
  8. Choose your capacity
  9. Now select confirm creation and choose Yes
  10. Now select Save and Exit and choose Yes
  11. It should reboot and you are done.
    Note 1: If installing Windows to the RAID array and Windows doesn't pickup the RAID array to install to then you will have to have your RAID drivers ready (motherboard driver disc or the driver on a usb) and load driver. (bottom left corner)

Excellent post as usual, but I wanted to point a few things out. The disk part clean command doesnt wipe the drive, it wipes the paritions (yea i know, just clarifying) and the stripe size for hte RAID should be much smaller than 128K. The lower the stripe the better the small file reads/writes will be. If you are mainly gaming and running windows on it, use a 16K stripe.

Thanks for the responses, so 16K stripe size?

Also is TRIM supported with RAID0? Read it might be but dont know if this ever happened.

Last I knew it was coming in an update, but as of now, no.

Yea, he only needs them wiped and doesn't need the drive formatted yet because he is setting up RAID so i though to simply give him a quick way to achieve the goal of preping them before the array tho even then that isn't needed when the array is made lol.

Can you link me to some info, I know usually the smaller the better for the OS, but with SSDs my buddy did a bunch of testing with two Corsair Performance Pros (I may need to test as well when I get another drive) but with SSDs 128 was the best overall.

Well its just common RAID knowledge, the stripe size is the size at which the RAID controller starts splitting the files between the drives. If you stripe it at 128K then only files 128K and larger get split and every file smaller is only getting the speed of 1 disk instead of 2. The speed will probably depend on the RAID controller but in general, smaller stripes for OS and programs, and larger stripes for data storage.

i can't remember exactly where i saw this, theres someone benchmarked his drives in raid array using different strip sizes and the 128k came up as the best overall

You guys might be right, I was just giving the facts about RAID, lower stripes should be faster. What methods were used for hte benchmarking? Were they using RL situations or just benchmarking software? It may be the raid controller or just something about SSDs that I don't know but definitely something to look into.

No need to post..Sean's already here biggrin.gif 128 stripe size IS best.Can vouch for..Then again..I move lots of stuff around..
