I recently removed a hard disk drive from an old PC, backed up the files I wanted, and formatted it. CrystalDiskInfo reported that the drive was healthy, although I had to rely on an AI explanation because I'm not very familiar with all of its indicators. Since AI-generated interpretations can be wrong, I'd like some real-world opinions: is this kind of HDD lifespan typical, or is it unusually long? How old are the oldest hard drives you're still using, and what condition are they in?

There’s a lot of variation. Some drives fail after only two or four years, while others survive more than 20. Age alone doesn’t tell you the current condition, and even a drive with good SMART data can fail unexpectedly. Keep reliable backups and don’t treat an old drive as the sole home for important files.
I’ve had an SSHD running for about 11 years with roughly 40,000 hours on it. It’s a little louder now but has had no actual problems, despite being used for gaming, video recording, and previously as an operating-system drive.
If the drive is only used for replaceable data and your backups are current, it’s reasonable to keep using it until it fails. For important work, a proactive replacement around six years can reduce the risk and inconvenience of an unexpected failure, especially if restoring from backup would take a long time.
Drives lasting 10 to 20 years isn’t especially unusual. If a hard drive makes it past roughly five years, it may continue running for a long time, although there’s no guarantee. Laptop drives tend to be more vulnerable because they’re exposed to movement and impacts.
I’ve had several drives reach 11 to 16 years, including older Samsung and WD models. Some are still used for games, movies, general files, or backups, but not for anything irreplaceable. I also have an external drive approaching 10 years and a couple of drives from around 2004 that still work.
I have a WD Black from around 2012 that’s still running in my NAS. It doesn’t get treated as the only copy of anything important, but it continues to work fine.
That isn’t always predictable, though. We had several enterprise drives in a RAID system begin failing within about a year of one another, and eventually two failed at once. Fortunately, the replacement server was already prepared.
