While the PC enthusiast community at large welcomed
news of SSD TRIM command being made possible in RAID 0 setups, provided Intel 7-series chipset RAID controllers are used, users of Sandy Bridge-E HEDT platform, running Intel X79 chipset, didn't. The feature was advertised to be initially available only to users of 7-series client chipset (such as Z77, H77), with Rapid Storage Technology (RST) driver version 11.0 and above. Intel made amends by announcing that users of Intel X79 chipset will be able to take advantage of TRIM command in RAID 0 setups, with a future version of RSTe (Rapid Storage Technology Enterprise) driver, without being specific about the version or its release date.
Said Intel in its note, "Current RSTe drivers specific to X79 do NOT support TRIM on RAID 0, but an updated RST driver version coming soon will add support for X79 based systems, including the TRIM on RAID 0 feature. Note that on client 7-series chipsets (non X79), RST driver version 11.0 and beyond supports TRIM on RAID 0."
