Please don't top-post ;)

I get 12 MBytes/s (sorry for the capitalization confusion)
because I'm using a ATA100 drive in an external USB2.0
casing capable of 480Mbit/s. I actually reached just over
50MBytes/s under Windows.

Same setup gives 24 MBytes/s under FreeBSD/i386 and 12 under
amd64. atausb does not make a difference...
