I'm not sure what you're looking for here, but:

I  currently have 245 volumes off-site; I back up or archive 1.95 TB per
day and copy for off-site storage; most of this occurs after 18:00 local
time, and to copies need to be ready to go by 07:00 the next day. In
addition, I back up or archive about 1 TB that does NOT get copied for
off-site storage -- so I run about 5 TB through the drives in about a 10
hour wall-clock period. The drives are all IBM LTO-2 (EXB up there is an
old 20 GB DAT drive I use for testing from time to time)

Dang!  That's a lot of drives per slot.... Or is it? It's twice the
ratio I've got, and if I had all 8 drives of the same drive type, I
think I'd have some running room, even.  (cross fingers, the PO goes
in today?)
