Question Harddrive ususally hot and noisy.

[esrever]

I have a 5TB HGST Deskstar NAS 5TB 7200 RPM in my PC and it's been running for 3 years.

It has always made clicking noises when in use even when I bought it but has been running fine almost 24/7 for 3 years.
Recently I noticed it has been getting very hot, 50C+ easily without doing much. It also started to not only click when in use but vibrate randomly.

SMART is fine but I am worried about it's longevity. Should I be worried?

The data is being backed up to my server so it's not a huge deal if it fails but I am thinking about preemptively replacing it.

Here is a screenshot. It cooled down a bit but it was 55C.

Better to replace a hard drive on your terms, rather than reacting to a complete failure.

If you catch it before it fails, you have the advantage of being able to image the existing drive to a new unit, and just going on as usual. If you wait until it fails, you're going to have to reload the OS, and restore the data--something of a pain, if you ask me.
