I think you're probably right on this count...a $50 dollar disk (even if it goes
down in price quite a bit in quanity) is NOT the kind of thing you want to be
distributing NeXT-Moria on.  Perhaps we'll see a SCSI-based floppy disk at some
time in the future for this machine (It DOES have SCSI, doesn't it?)

Well, I don't think it will necessarily take two 256k opticals to backup a 330
MB drive, considering most good backup programs do some kind of compression
on the data while moving it to the backup media...and usually, one doesn't
backup the entire system every time.  You do a total backup once, then
incremental backups every so often afterwards.

What confuses me is, the last time I heard, R/W optical disks had a definate
limit as to the number of writes that could be done...eventually, they just
stopped taking data reliably after ~n number of writes.  Is this a problem
with the NeXT drives...I hope not, since I've heard talk of swaps being done
to the drive when it's the sole mass storage device.
