I'm not real familiar with SCSI drives so I have a question about their
performance (actually it's on the controller).  When you run MFM or RLL,
the controller can only read or write one device at a time whether it is
a hard drive or floppy.  One database vendor suggested putting database
files or separate hard drives to increase performance.  I protested that
it wouldn't make any difference unless the drives were on separate
controllers.  Does this apply to SCSI controllers as well or does it
access drives simultaneously (or almost so)?
