Shame the documentation on this matter is unclear then. It does state in the release notes as pointed out by others TRIM is supported in RAID 0
If that statement from Intel is 100% accurate, then it is explicitly saying that TRIM commands are being sent to individual drives that are in a RAID-0 array. The wording could not be clearer. It is not saying that it passes TRIM to the array, but to the individual drives themselves. I guess us RAID-0 SSD nuts have been waiting so long for this that we expected more of a fanfair, but, TRIM in RAID-0 is apparently here...
Finally some hard evidence from a guy who does Bios Mod himself , Fernando has finally proven that YES Trim its working only in Windows 8 using Bios OROM v11.5.0.1414 for Intel Chipset Raid and Intel RST(e) drivers v11.5.0.1184.

Thank you fernando.
Yes my friend , i won't change w7 for w8 only for Trim support. Let's keep on researching maybe theres a way , last thing we loose its hope !
It's not yet 100% proven, but there are some important signs, that the Trim command really is active within the RAID0 array while running Windows 8, if the system is using the said Intel OROM/driver combination.
Neither will I. Unless that abhorrent Immersive UI and the Windows Store are able to be completely removed (which, of course, Microsoft will never permit). I continue to hope for individual drives in a RAID 0 array to be able to use TRIM on Windows 7, and I believe if Microsoft and Intel wished to make it so, it would happen.
Great to see you made it here Fernando and Welcome to Guru3D , i will be testing that latest OROM ROM 11.5.01414 and RST v11.5.0.1184 , will post back results later .

It wont let me update to Intel Driver RST 11.5 , the system says it's using the latest driver and it's up to date. I will now re-install w7 x64bit installling RST Driver pressing f6 during w7x64 fresh installation and i will report back in a few hours.

Much more ballanced performance across. Very stable so far. I will hammered it with a lot of work and benchmarks for one week to see how the performance has degraded , or if by miracle some kind of TRIM or garbage collection its past trhu the Raid0 but as simple drives and not as a Raid0 array , time and testing will tell us next week wednesday 25th of July i will post the same benchmarks AS SSD and ATTO to see how far degradation has taken this array in one week thru hell. -------------------------------------------------------------------------- Test # 3 and conclusion. 7/25/2012 10:34AM One week has passed since i have started torture testing my Raid0 array , testing mode used as follow: 3 consecutive runs of each benchmark 5 times a day for a whole week AS SSD , ATTO , Cristal Disk , Anvil Storage Utilities , HD Tune , HDD Tach , Lots of writes and Lots of Reads + Large transfer files of BR Movies and huge pictures from diferent drives to and from the Raid0 array non stop for hours on end each day for 7 days , drive was used 24/7. Here its the real time performance of the same Raid0 array of 2x 128 Samsung SSDs on Intel ICHR10 x58 Using Intel Raid ROM V.11.5.0.1414 , Intel RST Driver 11.5.0.1184. AS SSD By chispy at 2012-07-25 ATTO By chispy at 2012-07-25 Final Conclusion and my own opinion / understanding: YES some kind of Trim and or garbage collection its working under w7x64bit restoring performance back to optimal speeds , It is to my opinion and understanding that under w7 x64 there some new files within the driver that Fernando discover earlier namely C:\windows\system32\DRIVERS\iaStorF.sys , this file its some kind of new filter for the function of the new 11.5 RST Driver , this filter must be seen the SCSI device in the Raid0 array as single drives and passing TRIM and or some kind of Garbage Collection as it is the only logical conclusion after the rigorous torture testing done for 7 days to this Raid0 array , i observe very bad degradation on Reads and Writes after the 5th pass of all the bencmark test , the system Reads went down to 294 max reads and 232 Max writes on AS SSD and ATTO , but once i let iddle for a couple of hours the Performance went back up and was completely restored to optimal speeds. I will try to contact Intel for an explanation and if they answer my questions i will post them here , feel free to do your own testing , im done with mine and i did prove to myself that yes definitely something its improving performance back after iddle time of about 2 hours of iddle system time. Feel free to discuss my findings and if you have a better theory and understanding with real data as proff + extensive testing please let us discuss here , Long live W7 x64bit :thumbup: By chispy at 2012-07-25
Look forward to you results Chipsy and thanks for taking the time to do this. Also cheers for the links for updating the Intel OROM, been looking for something like that for a while so an inexperienced user can follow. Slightly off topic, but if I do update my OROM do I lose my existing RAID 0 array and have to set it up and reinstall windows again ?????
No, no and no (only precondition: the updated RAID ROM version should support your SATA RAID Controller).
Cool, time to give it a try then Asrock are usually pretty good at updating the Raid ROMs in new bios updates, im currently at 10.8.0.1303, i've noticed that the z77 line of boards received an update last week for their Raid ROMs (dont know which version), but not yet had this for z68.
Yep - the Z77's now contain Intel OROM v11.2.0.1527 I found I got the best results so far from the Intel RST driver v11.2.0.1006 with OROM v11.2.0.1527. I am extremely close to the maximum performance I can possibly get from 4 x 80GB Intel X-25m in RAID0 (using the Intel ICH).

Guys i keep hammering the Raid0 array daily torture test , with all benchmarks available , also doing a lot of writes and reads all day , transfering huge images , pictures , BR Movies and what not , you guys will be surprised at my findings next wednesday i will have some proff , until then i will keep the torture going non stop , to check for Raid0 degradation in performance if there is any
This is what I got from 2x 128GB Samsung 830 SSD RST 11.1 No clue about the BIOS - the disks are about 55% full and I used 32k Stripe size Actually here is an ATTO as well.
Look forward to the results !!! I updated my OROM to 11.2.0.1527 (from 10.8.0.1303) and i'm using RST 11.2.0.1006. Now my Array is about 3 weeks old, so my initial benchmark after updating the OROM was down on Seq reads from 1060mb/s (when installed the OS 3 weeks ago with older OROM) to 965.5mb/s (after updating OROM yesterday and 3 weeks use) with same driver 11.2.0.1006. However last night I ran the benchmark again and got Seq reads of 1036mb/s I wonder if my drive had been trimming itself ? Or whether the drives GC had done that ? (it had been sitting idle for an hr or so in the afternoon)
i will update my findings later today , heads up new WHQL Raid Driver : http://forums.guru3d.com/showthread.php?p=4371678&posted=1#post4371678
*** Updated My Post Number 30 with my findings and conclusion after extensive testing and data collection with Regards to Trim and or Garbage Collection on W7 x64bit , a big yes it is working.
