yum.  i don't in general remember my symmetric s/375 with fondness, but i
do remember wjolitz explaining to me how formatting the st506 drive with
1024 byte sectors saved on inter record gap.  as this was before ffs had
clustering, it also sped up the file system.  macintoshes of approximately
that era had the ability to format their scsi disks at 1024 bytes/sector,
too.  i think it's a shame that bsd hasn't kept up with those tricks.
