Guess I just didn't look hard enough or in the right place. I only spent a
minute or 2 on it, but yeah ATA drives don't tell you that sort of thing,
they say stuff like "ATA133 for a max transfer rate of 133 MB/sec *" then
at the bottom the * says something like "133 MB/sec burst rate from drive
to controller" or something similar. But I did try fairly hard to find
specs on our Seagate drives and couldn't find a hard number that told what
the maximum read and write speeds were.
