Intel Brings TRIM to RAID-0 SSD Arrays on 7-Series Motherboards

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.

As soon as I got confirmation from Intel, I fired up a testbed to confirm the claim. Before I get to the results, let's have a quick recap of what all of this means.
