Of course, U320 is passé now. State of the art in SCSI is U640,
although that's largely been ignored by the martket in favour of SAS,
which should be significantly faster in time. The limitations of PCI
bandwidth mean that there's little point in heading down that route
without PCI-X or PCIe (which can scale to over 1GB/s)
