I would be grateful for advice as I spec an i7 980x build for FSX. I am buying a SATA III MB (Asus P6X58D). Now that Windows 7 and Intel apparently support TRIM for RAID 0 SSD's would a pair of SATA II 160Gb Intel V2 SSD's in RAID 0 be better than a single 256 MB SATA III Crucial RealSSD? If I buy a small SSD for the OS (Win 7 64-bit) does that get TRIM support too? There is not too much difference in price but of course extra storage would come with RAID 0. I am however unsure about the performance difference.Thanks for your opinionsStewart

Seems I was mistaken and TRIM remains unsupported for RAID arrays. Back to the drawing board.....

Not sure why you changed your mind, but Intel does indeed support both RAID and Trim simultaneously. The driver you need is here.

Thanks, I had looked at one forum which siad you could TRIM RAID 0 SSD's and then they said you couldn't.I have asked for a quote, will be expensive but I only change my pc every 4 or 5 years.

There is always the question of how many cpu cycles are taken up the RAID array when using software RAID as opposed to a hardware solution? Perhaps with a 980x this is a moot point?

I use SSD intel for FSX drive , and 7200 rpm WD harddisk for OS .I think RAID 0 have risk to lost everything.

Yes with RAID 0 if one disk fails you lose everything. AS RAID O remains unsupported with regards to TRIM I decided to have a single Intel SSD for my 64-bit OS and the new Corsair Force for FSX. If TRIM ever gets supported for RAID then I can always change in the future. Stewart

If you use the SSD just for FSX, then I don't know that having/not having TRIM is that big? Or do you have to have your OS on SSD as well for there to be a significant difference due to SSD? At any rate, anandtech did some testing of Intel SSD on RAID0 and in some tests got great results. Don't know how that translates to FSX though. scott s..
