    Dan Snyder, PR Manager of Intel Corporation confirms that TRIM in RAID0 arrays is now supported on


    • Windows 7 and 8 (latter has been confirmed to work as well, see sources)
    • only on Series-7 chipsets
    • with Intel RST drivers Version 11 (11.2 or most recent 11.5 that still seem to be buggy).

    This means that previous generation Z and S users (all that are not Ivy Bridge laptops with Core i-3xxx CPUs) with SSD RAID configurations will NOT see TRIM working on their setups in the future. This is very disappointing for Z1, Z2, S, SA VAIO owners that use a RAID0 configuration.

    German win-lite forum member Fernando tested different Option ROM (Part of the computer BIOS) and Intel RST driver combinations on a Series-6 and Series-7 based board. Eventually he came to the result that the Series-7 chipset passes TRIM to the SSDs part of a RAID0 array. The Z68 based board he used does not pass the command to the member SSDs regardless of which Option ROM/RST driver is used (even the latest 11.5 ROM and driver did not add the functionality).

    Too bad My Z2 won't benefit from this.

    What exactly does TRIM do? I read a little bit that it collects trash from the SSD, I always assumed this was actually running in Windows 7 and working on our Z models, so we never had TRIM before?
    How much does this actually affect us, will our SSD lifespans be significantly short due to lack of TRIM?

    but i can't confirm Trim Support on my VPCZ1.

    Bumping the thread. I'm guessing there's been, and won't be, a solution - regardless of Intel driver, Windows 7 or 8, etc?

    Is it of any value to split the RAID array into individual disks and do it as a software RAID in Windows? Probably a bad idea, I'm guessing.

    Would imaging and writing the image back (Ghost, etc) "clear" the SSD every few months and be a "viable" solution?
