In my
experience, on/off cycles kills equipment much faster than
long "on" times.
Is that biased by the experience of failures that appear when
equipment is powered-on? One would seem to be shaped by simple MTBF, the other
by some
sort of electrical or mechanical surge.
The other has a lot to do with thermal expansion and contraction,
and the resultant simple physical fatigue.
