I've run a great mix of nonDEC SCSI drives on the 3100s I have and the
CMD interfaced MVII. For MFM I've tried everything I have most are
smaller
than RD53s though but they worked.

Depends what you have and what interfaces, usually it works fine.

Finding a U2Wscsi for a nonPCI VAX or ALPHA would be real tough.
Though Qantum fireball (scsi-II) at 5.1gb worked fine when I tried it
as a non boot disk on the M76 running VMS7.2. I tried it for laughs
as I was pulled from the server (p133!).
