I find it to be consistent. Bunch of tests below: note that my ATA33 tested
a little less than 33% compared to my ATA100 on the same Win2K system (makes
sense). I have seen odd numbers once in a while, but I assume the HD was
distracted by another background task.
No axe to grind, but it seems like an fast, easy, accurate, and cheap (free)
way to compare HD speeds and do other stuff too.
