I just bought a Kingston HyperX SSD 240gb drive for my computer. My mobo only supports sata 2, which is 3.0.
The sequential read/writes is estimated to be 525/480 for sata 3 connections.
I understand that there will be a decreased performance for having it downgraded to 2.0 but here are my results for CDM 3.0.1 x64

---------------------I know the numbers for everything else just blow the barracuda away, but the read and writes aren't too far off.
Can anyone explain this to me? Thanks.
