On 16 August 2012, AnandTech Lal Shimpi stated in his article titled Intel Brings TRIM to RAID-0 SSD Arrays on 7-Series Motherboards, We Test It, the following: In an unusually terse statement, Intel officially confirmed that the ATA TRIM command now passes through to RAID-0 SSD arrays on some systems running Intel's RST (Rapid Storage Technology ) RAID driver version 11.0 and newer. The feature is limited to Intel 7 series chipsets with RST RAID support and currently only works on Windows 7 OSes, although Windows 8 support is forthcoming.
In this article he does not mention at all which version of the Option ROM that is required, being part of the BIOS.
I am running Windows 8 Pro on an ASUS P8Z77-V Pro, Intel Ivy Bridge Quad i7 3770K, with the latest BIOS, which is 1805 on two Intel 520 60GB SSDs in RAID 0 connected to the Intel Z77 Express Chipset SATA 6.0 Gb/s ports (gray). The Option ROM version in this BIOS is 11.0.1339. My Intel RST driver which I installed prior to loading Windows 8 pro is 11.7.0.1013.
My question: Is TRIM being passed at all, I mean all the way to the RAID 0 SSDs on my system?
