I have spent the past three months evaluating ST506 drives, and I have
the following recommendations to make, in order:

	Micropolis 1304		(30ms, 50Mb)
	Quantum Q540		(45ms, 40Mb)
	CDC 9415 "wren"		(45ms, 35Mb)

My criteria were, in order:

	reliability
	capacity
	speed

I had problems with the Maxtor XT-1000 series (there are two on my desk
next to me, the XT-1065 and the XT-1105, 65 and 105Mb respectively).
They generate lotsa errors, and run real hot. They also hacked the
ST506 interface. They use the low current line for another head select,
and unless you can convice the controller to never set that line true
for the XT-1065, you can't use 'em.

P.S.	This is personal opinion, and should not be construed as a statement
