My Mushkin has run without incident on my C2D laptop (I think it's the ICH8M). Speeds drop from 123MBs Avg on my 1155 system to 94MBs Avg. I'm using the RST drivers as well.

The Sata II ports on the 1155 rig were good for just as much speed as the Sata III ports, so maybe the much slower laptop helps stability. I couldn't even get my AMD system to boot with the drive attached to a controller... which is strange (it's the 710 SB).

I certainly don't think it's every SF2281 drive, but I think some hardware just doesn't work with the drives due to defect, or of out of spec hardware, or one of twenty other reasons. Until and unless this drive doesn't work with any hardware I have, I won't be giving up on it. So if it's not stable in this laptop, then I get a PCIe Marvel 6G controller. If that doesn't work, then I start thinking about more extreme options.
