Should I be concerned that my HDD, which seems to be working fine, is 8 years old? (lemmy.ml)

It appears to work fine (it contains my home partition for my main machine I daily drive) and I haven't noticed signs of failure. Not noticeably slow either. I used to boot Windows off of it once upon a time which was incredibly slow to start up, but I haven't noticed slowness since using it for my home partition for my personal files.

Articles online seem to suggest the life expectancy for an HDD is 5–7 years. Should I be worried? How do I know when to get a new drive?

Always assume your data is in N-1 places at all times.

Any drive can and will fail at any time, no matter how well it was working yesterday.

I've had people in with their entire PhD and years of research on one single drive, with no backup - just gone.

If your data is only in one place, it will be in zero places soon enough.

Disposable or replaceable data - which honestly is going to be 90% of your stuff - meh.

But anything that you need and couldn't replace, that shit needs backing up to AT LEAST one other place.

As for the rest - drives can fail slowly, or they can fail fast. When they fail slowly, you start getting a couple of disk errors here and there, and you may just be able to order one in time to replace it.

When they fail fast, they just drop like a heart attack.

There's no way to know in advance. If your data is safe, then you'll either be out a few days while a replacement arrives, or you'll be just about able to copy stuff across. At that age, I wouldn't trust it farther than I could spit it. It could work fine for years more, but the moment you rely on it for something important, it'll give out on you.
