I have a WD Black 1TB drive that did service as my main desktop drive for about 6 or 7 years.
After that it went into my server at home. It was used for various things. At this point it’s spent the last 5 years as the disk my DVR records to. (Because 5 years ago I was expecting it to die any day and didn’t want anything more important on it…) So it’s being continuously written and rewritten 24 hours a day, 7 days a week.
It’s now about 17 years old and has spent almost the entirety of that time powered on. It’s been packed up and sent on two cross country moves. Still kicking.
I have a number of WD Green 1.5TB drives that are nearly as old and still in daily use in the same server.
Maybe I’ve just had great luck, but I’d be more surprised by a drive dying sooner than eight years.
Under my desk right now is a too-underutilized-to-upgrade-NAS that has been spinning 1TB Western Digitals since 2010. Between RAID-Z2 and cloud backups, there's almost no reason to get rid of them except for performance, which doesn't matter here.
If all of your disks are about the same age, from the same vendor, it might be reasonable to replace them over time to mitigate the risk that a firmware or manufacturing issue results in them all failing around the same time. Many vendors have had firmware errors where counters rolled over and the drive becomes inaccessible (generally much sooner than 13 years though).
I have a 3TB Seagate from around 2009 that still works. It was shucked from an external USB enclosure and has moved desktops several times. Granted its use has been pretty intermittent. Right now it’s just sitting on my desk, as it often has.
I have some ~140GB SAS drives HP branded that are probably of similar age based on the capacity, and they still work… but again, they haven’t exactly been active for the last 15 years straight.
I just retired some drives out of my home array. 3TB WD Reds with 10.5 years of power on time, no logged errors. Ran them through a full block check and had no errors.
