Oh I did not realize that. Is that why 11.2 is faster for raid? But on the other hand 12.7 is much faster than 11.2 with a single drive.
I don't know the exact reason, but I suspect, that the Intel RST driver v11.2.0.1006 has been optimized for Intel RAID0 systems.
The measurable performance differences are quite small, if you compare different Intel RST and RST(e) drivers in AHCI mode, but remarkable, if you do the same with a RAID0 system.But on the other hand 12.7 is much faster than 11.2 with a single drive.
I have posted such a comparison of different AHCI and RAID driver version within the second post of >this< thread.

How come windows 8 has such lousy performance when compared to win 7. I don't use windows 8 because its such a difference.
there is a pretty big difference in performance look here: http://www.rwlabs.com/article.php?id=832 there is a direct comparison with a sandisk extreme II both win 7 and win 8.
RAID 0 is even a bigger difference look here: http://www.rwlabs.com/article.php?ca...2&pagenumber=5
@ B Gates:
To be honest: I only trust my own benchmark comparison results, because only the user himself knows, what he has done (or missed to do).

fair enough![]()
Sure did look here: 2 thru 5 drive arrays There is some stuff I've been able to establish that previous testing did not show and that will be coming out in the next review.
The bottom line with Haswell is that it is great in a workstation environment which fits everyone's profile for the most part because Queue depth levels are very low. If you are using Haswell in an enterprise scenario like a file, web or database where high queue depths are much more common then Haswell is not the way to go. It has up to 10 times worse performance in those server categorizes than Z77 with arrays of 2 drives or more, with the exception of workstation environment where queue depth levels are very low then Haswell is markedly better. You can also see this in CDM 4K:QD4 and 4K:QD32 testing too.

I'm benching a pair of CR EDITION SuperSSpeed S301 128GB SLC drives on Haswell as we speak. I will make a thread and post the benches shortly. I will do a windows 8.1 comparison too that will follow shortly.
TRIM over RAID on X58 is now enabled - in fact anything since P35 is do-able. Just a FYI if you're late like me!![]()
