Avoid the RD53 at all costs... it is the most
problematic of
the RD series drives. The RD54 in my experience is the most
reliable, and I have a number of them in machines still working.
I never had enough RD53s to form a statistically valid opinion.
Never had a problem with RD54s (and I guess I had maybe
a dozen running in the lab).
Yes, going to SCSI would be nice, but you can't
put one in
your VAXstation 2000...
Unless you use Wolfgang Moeller's modified ROMs - then I believe
that SCSI will work. (IIRC the modified VS/UV2K ROMs also
incoroporate the >1GB fix ... but it's been a long time since
I looked).
