Well, I'm pretty sure that the electronics haven't used 12V for a good 15 years
either; that would have been for the motors in ye olde 5.25" full-height HDs.
Note that your CD and DVD drives are half-height.  You do the math.  :)

Since the newer drives are all small anyway, nobody has to use a 12V motor
anymore, and the electronics are all 3.3V, too.

Neat detail, though.  :)
