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. 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).
