I'll echo what Mark has said.  We've deployed about 20 of these to our
customers.  Excellent in all aspects.  Be sure and double the number of
slots you think you need.  The cost is not much more, especially if you get
to the larger libraries (you've already absorbed the shock of the Advanced
Device Support).

Awhile back I described some of the performance we've seen with AIT2: Drive
to Drive transfer rates of 50 GB/hour, two streams and 100 GB/hour.

Shortage of 50 GB tapes at times is a pain, but that should clear up as
well.
