I've been told that the HP LTO-4 drives can ratchet back their
streaming speed in a linear manner from max down to 0, but I'm not
sure I believe it.
This person also said that the IBM versions can't do that, they
instead stair step their streaming speeds back in discrete chunks.
I'd be interesting in people's experiences here.
