That was probably the case a few years ago, but now I think
nearly all manufacturers take exactly the same mechanical
parts and slap on a different logic board.  There is still
the bottleneck with head position and since IDE is cheaper
you'll probably buy bigger drives that make this even worse.

Anyway, for most multiuser purposes you should max out
the RAM before considering spending more on the disk
controller and drives.  A database that fsync()s transactions
all the time would be an exception because extra buffers
won't help with that.
