If you have a SCSI hard drive, then writing from the HD to the CD-RW
is faster.  It's my understanding, as I don't have SCSI anything, that
the SCSI controller allows for a direct write from one SCSI device to
another without the main CPU getting involved.  This was not the case
with EIDE, the last I knew.  There have been a lot of improvements to
EIDE drives to improve speed and so I do not know if this advantage is
still significant.
