In real life situations, a 486 DX 33 can't do over 75k a second.  This is
with the IDE card from another computer that can easily 300k.  Same HD,
same card, just a POS computer.  :(

I know how much a spec sheet says a computer *can* transfer.  The question
is realy how much can it transfer when windows uses 13 calls just go get
the data...
