I believe that there's not enough difference to matter. There is always
enough of a chance of a failure that you have to be prepared for it and
pretty much all of the vendors have made bad batches. But, these days
they are good enough that if you don't abuse them with flakey power or
high temperatures, 80% or more will last until you want to replace the
equipment for some other reason (5 years or more). The ones that fail
will pick random times to do it, though.
and fluctuating temperatures. That is what the Google report and another
one found that drastically reduced life expectancy. Running drives at 60
degrees centigrade may or may not induce death in a month (cannot
remember whether they continued long after cooling was rectified) so
long as the temperature is stable. Fluctuating temperatures even at
30-35 range can kill a disk faster than a stable high temperature. Ain't
it nice that smartctl alerts you of a change in temperature?
