Just some results of testing the comparison of wd and ata:
Both bonnie tests were run on a freshly booted machine, P133,
64M RAM, running X and netscape, but only Bonnie active:
-------Sequential Output-------- ---Sequential Input-- --Random--

ATA 64 3237 69.0 2913 14.0 1409 9.4 2951 59.3 3043 11.6 55.9 2.4
WD 64 2556 54.5 2902 13.3 1457 9.7 1987 40.3 3082 13.2 59.1 2.0
It may be worth testing with a larger file, freshly booted, with no X
running.
For reference, here is output of dmesg from my system:
