Intel RST v11.0+ Drivers Support Intel SSD TRIM on RAID 0 Arrays


Intel has released a Rapid Storage Technology (RST) driver that enables the TRIM command for those using Intel drives with a RAID0 array. This feature has been many years in the marking, so this news will make many happy. 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. The only kicker is that it only works with Microsoft Windows 7 and with Intel 7 series chipsets. Intel is currently working on getting the feature to work with Windows 8.

“Trim on RAID 0 for SSDs is supported in the Intel RST driver versions 11.0 and newer. Currently available for the general public on Intels downloads site is RST driver version which offers TRIM support on RAID 0 compatible with MS Windows 7 OS on Intel 7 series chipsets (earlier chipsets NOT supported). Intel is also working on a future release providing support for TRIM on RAID 0 on Microsoft Windows 8 OS for Intel 7 series chipsets.” – Intel PR
