Breaking SSD RAID

post #1 of 7
4/22/12 at 5:28pm
Thread Starter 
So I have two SSDs currently configured in RAID. However, they are 180 GB each and I realize that I do not have to keep them in RAID and would much rather prefer the faster boot up time alongside having TRIM as an option. (I'm only using 60 GB total which is still only 1/3 of one of the SSDs). I will most likely use one strictly for the operating system and applications and the other one for games. Now, how do I go about breaking the RAID array? Do I have to reinstall my entire operating system all over again? Do I have to secure erase the drive? How do I secure erase each drive? And when I set to AHCI, how will I know which SSD will be the primary drive to use for boot. Basically I just want to know how to go from my RAID array to just having 2 individual SSD drives and my internal storage drive.

If it's possible to do it without having to unplug the two drives that would be nice. I don't feel like opening up the system to do it all, but if it is a must then I have no choice.

  1. Make a system image of the RAID array with todo backup: http://www.overclock.net/t/1227835/how-to-disk-and-partition-cloning-backup-restoration-migration
  2. Then boot into the RAID manager and break the array.
  3. Leave the SATA mode set to RAID.
  4. If you want you can secure erase if you like: www.overclock.net/t/1227597/how-to-secure-erase-your-solid-state-drive-ssd-with-parted-magic#post_16684060
  5. Restore the system image to either drive you like.
  6. Now you should be able to set up the second drive how you like.
  7. If you want to change to AHCI mode now you can do this: http://www.overclock.net/t/1227636/how-to-change-sata-modes-after-windows-7-installation

You need to go into the RAID config utility and destroy the RAID, then re install everything. You should backup everything you have before you do this. You don't need to erase either drive, just remember to make sure alignment is correct before you re install windows.

So if I break the RAID in BIOS, I don't have to worry about secure erasing the drives? Would they perform like new either way?

As long as you align them properly and follow sean's guide, the garbage collection process will keep them in tip top shape.

What do you mean align them properly? If I'm breaking the RAID and using them as individual drives, I'll have TRIM so garbage collection isn't necessary.

Just make sure your partition offset isnt bad. If it is you can lose a lot of performance. You shouldnt have to worry about that.

...TRIM simply optimizes garbage collection, if your SSD didn't have a garbage collection routine then TRIM would do absolutely nothing.
