great setup B Gates !!!
Very nice test rig...trip SanDisk Xtreme IIs, I expected nothing less...lol
Interesting....we both run RST 11.2. ;)
it doesnt matter 11 or 12 series orom the both work the same as far as performance goes
see this B Gates that happens to me since ages
2x ADATA SX900 256GB RAID0 128k stripe free space 349GB
RST 12.7

UNINSTALLED REBOOTED

but i still see this on devices

not sure if i should install 11.2 RST---will try and post what it gives
Great job Bill, been waiting to see how you did with them. Now I got to resist picking up a z87 mobo, dam. Thanks again bud... :clap:
the first benchmark shows that write caching is not enabled look at the 4k write compared to the second bench. I'm not sure if the iastorF affects anything but it has been my experience that it does not. Uninstall 12.7 and install 11.2 https://downloadcenter.intel.com/Det...?DwnldID=21408
use the exe so you have the rst control panel
look at the system report in rst control panel.
did you see this article? http://www.rwlabs.com/article.php?id=836
yes i already repetead this procedure since ages :) look
with RST 11.2

see those files are version 12.7 im kinda scared to remove them by hand...
I see what you mean. can you look in RST control panel at system report? it looks like this:

its also varies now increased...
RST 11.2

this is what u want

seems all ok right ?
yes seems perfect. I think device manager is wrong.
btw this is my system

According to my knwledge I suspect, that B Gates and not andressergio's Device Manager is wrong.Quote:

Bug: The iaStorF entries of the Registry will not be deleted by the uninstall procedure.
Bad consequence: The performance will drop, because the absolutely unneeded SCSI filter driver iaStorF.sys is still active.
For more informations you may read the "Switching from RST to RST(e) driversand vice versa" chapter within the start post of >this< thread. There you will find a link to the solution of the problem as well.
My experience is that even though Ive never used RST(e) I still have have iastorf:

http://i876.photobucket.com/albums/a...ps89b7c5c4.png
And I have used your procedure to remove it, which resulted in zero performance gain. I thoroughly tested to see if there was a difference and there was not. The thing is iastorf is there whether or not you have ever used an RST(e) driver. I have not.
Look at the rst control panel:

I believe this is correct. I apologize if I'm misunderstanding you.
Thanks Fernando and B Gates for the great help, i read your post Fernando but it send me to a link saying the same, i actually downgraded from 12.7 to 11.2 and YES i have that problem, so what i should do ? uninstall 11.2 then let windows use the native ones and delete files manually from both windows and registry ?
andressergio definitively had used the Intel RST(e) drivers, before he "downgraded" to the RST driver v11.2.0.1006.
Furthermore there are big differences regarding iaStorF between Windows 7 and Windows 8. Win8 doesn't use the SCSI filter driver iaStorF.sys at all, even if you install any of the RST(e) drivers.
Reason: Win8 and Win8.1 do support the UNMAP command, whereas Win7 doesn't do it. The TRIM in RAID0 feature requires the UNMAP command to let TRIM pass the Intel SATA RAID Controller into the RAIDed SSDs.
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.Quote:

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! :)
