Actually it's true, to a limited extent, with some disk drives...specifically
fast ones.  On a 1MHz Apple //, some hard drives can retrieve data faster than
the machine can accept it.  If the machine looks for the data coming off the
hard drive more frequently, it gets it faster.  Which makes the hard drive
APPEAR faster.  (Of course it really isn't but ACCESS is faster, which from the
user's POV is basically the same thing.)
