Actually, I don't think it involves any I/O -- the process is completely 
internal to the drive.

I think your next step is to dump *lots* of data by hand to the tape (or a 
couple of tapes).  Forget about amanda, and just dump whole tapes worth of 
data with your backup tool of choice (dump or tar, preferable).  See how 
that goes.
