Temps that shorten drive life

My drives are rated for 5C to 55C; I just asked Western Digital if there's a
temperature within the spec range at which their drive would experience a
shorter life. For instance, running in the 40's instead of the 30's. They
said this won't happen until above 55C. But I wonder if anyone here knows
differently? TIA.

No one has ever bothered to measure it, too expensive to measure.

The drive is specified to have a certain life at 55C - which explains their
answer. However you may see a longer life than specified if it's run cooler
than 55C. However the spread between drives is quite large so you may not
see any difference unless you have a few 100 drives to test.

55C is *way* too hot for a hard drive.

You should be aiming for max 40C - no more.

Bear in mind that these temp readings tend to relate to the actual
casing - at which stage the components on the logic board (which are far
more susceptible to heat damage) are probably twice the temperature.
(I.e. dangerously warm.)

I agree on this. And this should be at reasonable load.

For some drives it may need to be even lower. For example
I am the person with the about 40 Maxtors running reliably
24/7 for 3 years now. But they are in a server room and with
outside air on each, i.e. they don't go over 30C under
heavy load.

WD is lying to you. Some background: Semiconductors have
about 20-30 years lifetime at 25C. This degrades by a factor
of about 2 every 10C or so. Something similar holds for
mechanics, e.g. the ball bearing in the head mounting.

Bullshit. Manufacturers know the effects of heat on components and
use that knowledge for reliability and life span testing and
projections.

That clearly wasnt involved with that mindless claim WD made.

Its completely stupid to try to claim that there is no effect
of temp at all below 55C and an effect above 55C.

And what matters with hard drives is whether the reduced life is actually
seeing the life lower than the drives are actually used for other reasons anyway.

Any semiconductors that average only 20-30 years lifespan at 25C had to
be manufactured very, very badly or were among the 1st generation
EPROMs. 20-30 years would be for operation at maybe 10C cooler than
the maximum allowed junction temperature of 95C-200C.

Indeed

Are you drunk?

Maybe when you sober up in the morning you'll be able to articulate an
argument.

Well, depends. Actually it is difficult to get current information.
The figures are from Intel's memory components Handbook from 10-15
years back.

Nope. JUST that no one has bothered to quantify it with that particular drive.

No need to ask if you could ever bullshit your way out of a wet paper bag.

The answer is obvious.

Nope. You have no way of knowing what the engineers know or don't
know about their components or drives. You're just guessing and
assuming, as usual.

Any 2 year old could leave that for dead. Get one to help you before posting

There's a chemist's rule of thumb - if you raise the temperature
of a reacting system by 10 degrees (obviously not Farenheit, or Badley,
or other such archaic tosh), then you double the speed of a reaction.
Not strictly relevant to mechanical failures of bearings, but of
considerable relevance to things like the oxidation of lubricating
oils, the re-crystallisation of solders and the diffusion of dopant
atoms.
