I cannot verify that with my drive, but my largest is 18GB so maybe
the difference is not as pronounced as on some newer drives like those
(currently) monster 70GB drives.

A 70GB IBM Ultrastar supposedly can physically outrun the internal
electronics on the faster tracks. One review I read mentioned it as a
problem, though I'm not sure why. 

In any case, I'm not quite that picky, and I would not think that
postmark would benefit as much from being on the faster tracks. It's
doing a lot more complicated things than just streaming data.
