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.
