SSD on system running RAID 0

[Inaharry]

Hi everyone,

I'm getting a bit confused with different things I've read and I wondered whether anyone might be able to clarify something for me....

I'm using a Gigabyte GA-EX58-UD5 which is SATA2 ready to do a clean install of Windows 7 HP x64 and I've attached a Crucial M4 128GB SSD to port 0 along with 2 x WD 1TB Caviar Blacks which I got from OcUK this week on to ports 1 & 2.

Ideally I'd like to run the SSD as a single drive and run the 2 x 1TB drives in a RAID 0 to give me a single 2TB drive and benefit from any speed increase. I understand the risks of RAID 0.

However, I don't want to cause any problems with TRIM running on the SSD and I know that in AHCI this would be fine, but if I have the following configuration on the Intel Matrix Storage Manager:

SSD - Non Member Disk
WD 1TB Black - Member Disk (RAID 0)
WD 1TB Black - Member Disk (RAID 0)

....will that stop TRIM from working on the SSD?

I downloaded the RAID driver from Gigabyte (10.6.0.1002) dated June 2011 which I was going to use during the Windows installation.

If anyone knows, I'd really appreciate any help.

Thanks!

Thanks very much for the info and link Surveyor, that's the part I was getting confused on - whether it was just when the SSD was part of the array or even just being on a port where RAID has been enabled.

I did exactly what you suggested, I used the latest driver you linked to and once everything was installed, updated and configured, I attached the 2 x 1TB Blacks and put them in RAID 0. After checking TRIM functionality by using the 'fsutil' command, everything appears to be working.

Thanks again for your help, it's really appreciated!
