Update all your drivers, then test with other utilities like CrystalDiskMark ?

Nobody has mentioned anything about TRIM in RAID0 here. Now . . . we're talkin' about a Z97 motherboard, and I thought that eventually Intel was going to address the TRIM problem since the discussion picked up after my Z68 board was released some three years ago.

I've had a number of RAID configurations on various machines -- one still working in our house without missing a lick as RAID0 for the last six years. And following the enthusiast trend before RAID was generally available on motherboards or when we bought Promise Tech and other cards for the purpose, it was all about speed.

But speed is not much of a problem for a standalone SSD. For that, I'm not interested in RAIDing SSDs. Even the lower prices these days seem too much to pay just to double the speed of an SSD or an array of them when the difference is not even much noticeable.

Just my thoughts, since the OP is trying to make a decision.

TRIM has been supported in RAID0 since z77.

That's good to know or have confirmed.

Of course, I'm still thinking how HDDs went from 33 to 66 -- eventually topping out at half SATA-II limits after two decades. With SSDs and SATA-III, we almost double performance over those limits. If you RAID0 two SSDs as I recall, you come close enough to doubling again.

But at that point, I just don't think it makes enough of a difference to spend 2x or more on the SSDs. Of course, you get the capacity, but you're already close to "light-speed" with a caching program and a single SSD.

Just the way I'm inclined to think now.
