Que brutal...
Vieron cuando dice que los tienen a mayor temperatura ambiente, para mejor eficiencia?
No se me hubiera ocurrido, pero ahora me parece razonable, en el caso de discos duros.



edit: busqué y encontré esto:

Better too hot than too cool

Google's research found that temperature doesn't affect the reliability of hard drives very much, and certainly not in the way many people expect.
In the first two years of a drive's life, it is more likely to fail if it is kept running at an average temperature of 35 degrees C or less than if it was running at over 45 degrees C.
That's surprising, and it suggests that spending too much time worrying about air conditioning systems may be counterproductive — a warmer environment actually suits disk drives better.
From year three onward, disks running above 40 degrees C had a higher failure rate than cooler running drives, but could it be possible their higher temperatures were a symptom of their impending failure? It's not clear that that is the case, with Google concluding that "at moderate temperature ranges it is likely that there are other effects which affect failure rates much more strongly than temperatures do."

LPM, todo el mod que le metí al P180 para poder meterle airflow a los discos... :P

De hecho, todos los problemas que spin-up que ví a lo largo de los años, fueron siempre en días helados de invierno.
Las partes mecánicas se contraen unas micras con el frío.

Sin embargo al final también dice que después de los 3 años fallan más los que andan más calientes. Pero puede ser que justamente calientan más porque tienen otro problema y están a punto de fallar.


Edit 2: A quien le importa. Igual nos pasamos 100% a SSD y listo.
