I would like to thank ephraim for explaining clearly and concisely why
the drive is behaving as it is.  I want to state again that I have no
complaint with the DD50.  It is miles above what I had been using (and
would be somewhat faster if I could swap my Plus for an SE).

The bottom line: due to less than perfect hardware in the Plus and
bugs in its SCSI manager, the Plus is unable to take advantage of the
drive and its cache; and also because of its cache the Disktimer II
seek test results are meaningless.
