With today's modern SCSI drives, you'll find the next bottleneck is
the your 33 MHZ 32 bit PCI bus. If you're serious about going SCSI,
you'll need to upgrade your mobo to PCI-X. There are workstation and
server boards out there with embedded SCSI controllers, or you can add
a RAID controller to one with a PCI-X bus.
