I had a few drives running at about 55C for a couple years, with no 
failures (knock wood). These were used drives before being put into 
that environment, so they arguably had already survived the "infant 
mortality syndrome" that the google study identified. Would I 
recommend running drives at 55C? No, but I wouldn't be too concerned 
about it either.

I know of at least one manufacturer who voids the warranty if the drive 
exceeds 55 Degrees.

Care to name names? (Inquiring minds want to know!)

I have a couple of drives here that have the 
"Exceeded 55 degrees" mark permanently recorded in their SMART data now. 
Having said that, I've not had issues with them yet (they only have 
about 14,000 hours on them).

I'd wager that extended running at elevated temperatures has the 
potential to affect the bearing lubricant, but it's just an hunch. I've 
never killed a drive from overtemp (and in a couple of cases I actually 
tried).

That would be my guess as well, although I'm sure that there are high 
temp lubes available. Just depends on what the mfr uses.
