If your configuration can pull it off there is one way that really
makes the SCSI shine.  All you have to do is install two SCSI drives
and then try to balance the usage between the two drives.  That way
processes don't get bogged down because of other processes' I/O.
One interesting point was a benchmark we ran that performed lots of
work in two directories.  The increase in performance by putting
these directories on two seperate SCSI drives was very close to 100%.

It's becoming obvious that this is a religious issue.
