Also worth noting is that the "enterprise-class" drives have protection from
heavy load that the "consumer-class" drives don't. In particular, there's no
temperature sensor on the voice coil for the consumer drives, which means that
under heavy seek load (constant i/o), the drive will eventually overheat.
[There are plenty of other differences, but this one is important if you plan
to put a drive into 24/7 use.]
