one more _important_ piece of information.

these tests will only give you sustained data tranfer.  it won't give
you burst speeds.  the important consequence is that there's no way
(that i know of) to differentiate between a UDMA 66 and UDMA 100 drive.
i've been trying to figure out this one for awhile now.

reference: linux-kernel mailing list.  it's been asked many times.  it
may be in the lkml faq.
