I just purchased two Seagate 160gb sataIII/6.0G drives.(so says the label on them) I know my mother board is only SATA II. For some reason in the Raid setup they are listed as 1.5gb. I ran HD tune and the numbers were on the lower side, 166 burst. My Green 640gb 5400rpm drive actually had higher burst speed. the drives appear to have a jumper-like configuration on the input side but different from the normal M/S/CS configuration. Any insight on this would be helpful. thanks guys.
