Got another problem now... has anyone used the SATA3/6Gbps for RAID0? I have two Crucial RealSSD C300 drives and the RAID performance is worser than a single drive.

I've tried both IDE and ACHI modes, and latest drivers for the controller. It uses the boards Marvel 9128 controller btw. I cant even find anything on this board and RAID0 on the SATA3 controller from searching as hardly anyone has a SATA3 drive...
