The average application for most people is decidedly _not_ to have
bulk I/O, but large numbers of very small I/O operations. Like on
a news server, a mail server (using maildir), your typical web server
etc. Imho the seek times in SCSI drives is faster not only due to
rotational speed, but also because of more powerful arm moving
motors.
