I'd have guessed that. ;)

True. But since the 386, PCs are 32bit, for that fact since 1978
VAX was 32bit.. You would have thought a wider IDE or data channels
would have happend. But it hasn't.
IO devices often lagged the CPUs or were designed for the devices
convenience or so it seemed. I feel legacy, (not always PCs)
played distinct factor as well.
