Furthermore there are big differences regarding iaStorF between Windows 7 and Windows 8. Win8 doesn't use the SCSI filter driver iaStorF.sys at all, even if you install any of the RST(e) drivers.
Reason: Win8 and Win8.1 do support the UNMAP command, whereas Win7 doesn't do it. The TRIM in RAID0 feature requires the UNMAP command to let TRIM pass the Intel SATA RAID Controller into the RAIDed SSDs.
RAID 0 TRIM works with windows 7. I have never used a RST(e) driver just standard. Unless 12.7 beta is a RST(e) driver.
