I don't believe they use enterprise drives.  Most mechanical devices prefer
a consistent temperature, they are indifferent to hot or cold, they just
don't do well with all the expansion and contraction that occurs with
temperature changes.  Only the solid state portion of it would prefer cool
to hot, but typically the mechanical parts will fail before the solid state
parts, even in a consistently hot environment.
