Most consumer HDDs are made for normal use. Basically, the computer is turned on during the day, and turned off at night. So the typical duty cycle of the HDD is only a few to several hours in a given day.
I only just recently noticed that WD makes a series of HDDs for 24/7 use (these).
My question is: in a DVR or NAS (on 24/7), do these 24/7 HDDs last longer than traditional HDDs? Are they more reliable? Or is this just a mere marketing gimmick?
I ask because I've always thought that the greatest enemy for a mechanical device is the heating and cooling phase when turning on or off.
