Maximum safe hard drive temperature?
I have two new-ish 1TB hard drives in my server, both running at 38 degrees C at the moment. Should I be worried?
38C should be fine. A quick look at some spec sheets shows that operating temperature is 0C to 60C on many models.
You might be interested in section 3.4 of a study done by Google on hard drive failure rates. Temperature is not an issue in drives until they are a few years older, and even then, it seems, it's not much of an issue under 40C.
What does the manufacturer's datasheet/documentation have to say about temperature ?
