When my Datamac drives started to go flakey after four years of solid usage
(normal wear and tear; they exceeded the MTBF rating), I shopped around for a
replacement mechanism to retrofit the Tandon and Quantum units that Datamac
used in their drives.  The one I found was a Seagate ST-125, a 3.5" platter,
very quiet, 38ms access, 20mb drive mechanism.  I assume this is the same unit
that Applied Ingenuity is using (though they might be using the SCSI model,
I'm not sure).  I can't say anything about their total drive package, but I am
pleased with the performance of the ST-125 -- it is very fast, and very quiet.
I also hear that a 28ms access unit might be produced soon, and that should
really scream on an Apple.

(For those owners with ailing Datamac drives, installing the ST-125 wasn't
just a plug-in-and-go procedure.  I had to modify and burn a new EPROM for the
drive's controller board to handle the different cylinder and head count of
the ST-125.  FYI.)

I got my ST-125 at dealer wholesale for about $240, by the way.  That should
give you some idea of the kind of profit A.I. is making if they do indeed
use the ST-125.
