I have a motherboard with Intel C600. It has SSDs configured as RAID1. I know the drives themselves support TRIM, but I am not sure if the RAID driver software does.
Does C600 support TRIM with RAID1?
According to Intel(R) Rapid Storage Technology Enterprise version 3.8, this version adds support for TRIM in SSDs configured as RAID 1, 10 and 0. However this version has been only released for retail Intel(R) server platforms.
