Quote from prophet:
I always compare the MTBF (Mean Time Between Failures), and tend to stay away from any hardware that runs overly hot. Fans will add vibration and noise and can fail sometimes.
Excessive heat destroys most anything, be it hard drives, CPUs, engines, and biological life, especially anything with moving parts. Hard drives are particularly vulnerable to stress because they have moving parts and will make large swings in temperature between the idle, power down state and heavy disk access.
Iâd rather get less expensive 5400 RPM drives, or a RAID configuration, and invest in extra memory for a disk cache. Power consumption, noise and temperature will all be lower, and your data will last longer.
