    You need to adjust your frame of reference. 7200rpm consumer-type drives,
    regardless of interface, are not going to be faster than the
    state-of-the-art in server or workstation-class disks at DOUBLE the
    rotation rate.

    Speaking of interfaces, I would expect SATA to eventually scale beyond SCSI
    but at this point the first version of SATA is slower than U320, I think.
