Logic?
Mechanical devices have decreasing MTBF when run in hotter environments,
often at non-linear rates.
Server class drives are designed with a longer lifespan in mind.
Server class hard drives are rated at higher temperatures than desktop
drives.
Google can supply any numbers to fill those facts in, but I found a
dozen or so data sheets for various enterprise versus desktop drives in
a matter of minutes.
