I'd like to see figures on this. My experience has been that
hardware-based compression is both faster and more efficient than
software-based
of hardware and how that manufacture/engineer designed things.

I recall being told or reading (a long time ago) that the algorithm used by
3590 tape drives is the same as used by the adsm/tsm client.
My aging notes on this indicate that the client uses Ziv Lempel (LZI)
and the 3590 uses a Ziv-Lempel technique called IBMLZ1 - which would seem
to be the same
