Forgot about HWINFO64. Good proggy, but it reports the same.
Intel 82801HB ICH8 - SATA RAID 0/1/5 Controller [B2]
Actually, I'm doing okay with RST 11.7. It seems to be stable, supports TRIM, doesn't mess up AnyDVD or my DVD in general, and doesn't crash or do bizzare things during online capacity expansion. I have read some reports of other people having issues with it, but not me.
I tried to install 12.5 because I wanted any bug fixes, and liked the new performance tab and the fact that you could change some of the disk write cache policies directly from the RST UI rather than burrowing into Windows Device Manager. Big mistake though. I'll take the stability of 11.7 over a few handy UI improvements and MORE bugs.
