Raid0 and TRIM Support on Intel 11.5 OROM and Latest v11.5.0.1184 RST Drivers ?

[andressergio]

current setup:

great setup B Gates !!!

Very nice test rig...trip SanDisk Xtreme IIs, I expected nothing less...lol

Interesting....we both run RST 11.2.

are RST 11.2 better than new 12.7 ?

[B Gates]

are RST 11.2 better than new 12.7 ?

Yes 11.2 is faster for RAID 0. 12.7 is faster for a single drive.

[andressergio]

Yes 11.2 is faster for RAID 0. 12.7 is faster for a single drive.

wich RAID ROM its needed for 11.2 ? same ?

Thanks mate !
Sergio

[B Gates]

it doesnt matter 11 or 12 series orom the both work the same as far as performance goes

[andressergio]

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

[DooRules]

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...

[B Gates]

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.

yes i already repetead this procedure since ages look

with RST 11.2



but i still see this on devices





see those files are version 12.7 im kinda scared to remove them by hand...

[B Gates]

I see what you mean. can you look in RST control panel at system report? it looks like this:

[andressergio]

its also varies now increased...

RST 11.2




this is what u want



seems all ok right ?

[B Gates]

yes seems perfect. I think device manager is wrong.

[andressergio]

yes seems perfect. I think device manager is wrong.

will i live it that way B what you think ? its more score than i been having and its fast...for only 2 drives on RAID

Yes that looks really good.

[andressergio]

Yes that looks really good.

Thanks for your fast help B !!!
Cheers !!!

btw this is my system

[B Gates]

btw this is my system

looks great! thats one hell of a radiator you got there.

lol yes has to hold the 3x GTX680 SOC + my IVY at 5GHz HT

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

@ andressergio:
Your Device Manager pictures show a typical issue, which may happen, when the user is downgrading from any Intel RST(e) drivers v11.5 or higher (containing an additional SCSI filter driver iaStorF.sys) to any "classical" Intel RST driver using just the iaStor.sys.
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:


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 ?

[Fernando]

My experience is that even though Ive never used RST(e) I still have have iastorf:

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.

Enter the Registry and delete the iaStorF entry as written by Squall Leonhart. Don't try to delete the iaStorF.sys from within the Windows\System32\Drivers directory! You will get a BSOD while trying to reboot after having done that.
