Intel to Finally Provide TRIM Support in RAID0

By - Source: StorageReview | B 27 comments

Intel set to provide TRIM support for Rapid Storage Technology (RST) based on its 11.5.0.1109 Alpha release notes.

For those SSD users that have stayed away from running a RAID setup due to lack of TRIM support on their SSDs, Intel looks to be finally addressing this concern. Based on information listed in its 11.5.0.1109 Alpha release notes, Intel will be providing TRIM support with the final driver release.

"2. This release will not enable the TRIM on RAID0 feature, but it will be added in the next RST 11.5 release.  Contact your RST AE representative with questions."

TRIM is a command that allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally. The command improves the efficiency of your SSDs internal Garbage Collection (GC) and helps reduces write performance degradation. This function was not available for a SSD in a RAID setup.

    Well, I hope to see some real world tests here on TH soon.

    Will trim support be only on RAID0. Wonder if they will support trim on RAID1?

    This is excellent news, but I have to ask, is this a chipset update? Or is this just a driver update? Or maybe even a bios update for older chipsets? Will my old p55 board be able to enable this feature?

    This is waaaay overdue.

    It's only an issue with striping on SSD's

    Finally!
    Only reason why I buy mass SSD's is for the raid feature.
    This is bonus material to me.

    I was under the impression that most 3rd gen SSDs are in fact capable of RAID 0 already. I bought an Intel X25M 80GB, and I know that doesn't support it, but it seems to me that the Sandforce SSDs are already able to do it...? Am I off my rocker?

    Also, in case people are unaware, you can run your drives as RAID via BIOS, with a RAID HDD setup and a single SSD. That's what I've been doing. Just need RST installed.

    With black friday coming up I might have to opt in on a bigger SSD this year... hmm...

    Intel RST is a driver, and also a program that runs in your windows tray. Just download and install.

    You can run a SSD in RAID0 but you do lose TRIM support. 3rd gen SSDs have better GC (garbage collection), which do a manage the same aspects as TRIM better (though TRIM still makes GC more efficient) than 1st gen SSDs did.

    So, does this driver let an Intel X25-m G2 SSD be able to accept the TRIM command when in RAID 0?

    So, if I set my drives to IDE, rather than AHCI, set up my raid 0 configuration, and install the latest RST drivers (when they're released,) TRiM should be enabled by default?

    The problem I have with intel drivers, and windows, is that it's so damn hard to verify whether or not particular features are running on your hardware -.-

    It would be interesting to compare the difference of a SSD running by itself, versus 2 setup in Raid0. Wonder what the difference in performance would be.

    Raid 0 owns. Makes it almost 50% faster. Big thanks to intel for fixing this.

    Most likely just a driver update thats needed, the trim itself have been available for quite some time in the ssd's firmware. Cheers to Intel for finally making the raid driver trim enabled.

    In real world performance it helps for sure but not near as much as synthetic benchmarks would suggest. Running 4x ssd in raid0 atm.

    Ït should as long as the driver have the necessary firmware to support it on a drive level.

    You set your drives to RAID, not IDE or AHCI. I think the AHCI driver and RAID drivers are similar, with RAID allowing multiple drive setups.

    Ah yep, this is what I meant to say, silly me.. Odd that this has always been a software/driver issue, rather than a hardware issue though, not that I'm complaining, this is great news! Now I can finally revert back to a RAID set-up without worrying about degrading performance over time :D

    TRIM should be implemented at the OS level...blame Microsoft for this one

    Some of you didn't read the attachment... it's not just a driver update. (4. The RAID OROM version for this release is 11.5.0.1111, the driver and user interface version is 11.5.0.1109.) So your motherboard manufacture is going to have to do an update. Most of the newer boards will be fine. I do know that my x-58 is going to require a update as it's running 10.5 on the raid orom.
