There is sth wrong with the RAID controller on that mobo. I have 2x120GB SATA in port 1 and 2 (RAID0, 32kb stripe) and 2x160GB SATA II in port 3 and 4 (RAID0, 32kb stripe). I'm running Windows XP 64. The trick to turn off read caching and command queuing is decreasing my performace Moreover my SATA II drives are set by Windows to be 1st generation of SATA Please look at performance of my drives, my old 120GB drives are reaching 204.3 MB/s but these new SATA II drives only 196.8 MB/s.
