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.
Either at the client or at the drive, it is just running data through a
program...
but this would tend to support different possibilities based on what piece
of hardware and how that manufacture/engineer designed things.

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 compression.
