I recently got my hands on several hard drives for my NAS setup (an UNAS PRO). They're all the same model (ST3000DM007-1WY10G) but have varying powered-on hours:
- HDD1: 8759 hours
- HDD2: 57770 hours
- HDD3: 8634 hours
- HDD4: 21423 hours
- HDD5: 57341 hours
- HDD6: 57340 hours
- HDD7: 57341 hours
While none show bad sectors and they were free, I'm curious about how much life I might get from these drives given their hour counts. They're set up in RAID-6 for redundancy, so I'm hoping for some feedback on their longevity. Thanks!

It's hard to pin down exactly how long they'll last, but you can check resources like Backblaze for failure rates and lifespan data on similar models. They have a ton of data since they monitor so many drives.
Just a heads-up, hard drives don't actually get hot enough to 'cook' like food. That said, I wouldn't keep drives with those hour counts for too long. HDD1 and HDD3 are pretty high, and generally, I wouldn’t trust anything with that much use; I've had some fail around that mark.
I've seen hard drives hang in there for way longer than expected! You might want to run Crystal Disk Info to get a better gauge on their health.
Honestly, those hour counts aren't too bad compared to some drives I've got. How do you know HDD1 and HDD3 have been replaced? They could just have been moved to storage. I've got drives with even higher hours still running fine!
