I installed a 500GB hard drive salvaged from an old Lenovo ThinkPad into my desktop. A disk-monitoring tool reports 100% performance but only 67% health. How quickly can that health rating decline, and is there a specific point where the drive should be considered unusable? I'm thinking of using it for a media server, storing Twitch recordings, and perhaps a few older or indie games—not anything irreplaceable.

It’s fine as a low-risk storage drive for replaceable media or games, provided you maintain backups of anything you care about. Old laptop drives were often used heavily and may have lower endurance than enterprise or desktop models, so I’d treat this one as disposable. Run an extended SMART test and a full surface scan, monitor the error counts, and replace it if they increase or the drive starts behaving strangely.
Hard drives can fail at almost any age. Some die early, while others keep working for 10–15 years or more. Warning signs include very slow file access, repeated read errors, disappearing files, clicking or grinding noises, and rapidly worsening SMART values. If you notice those, replace it rather than waiting for a clear cutoff where it becomes unusable.
There isn’t a reliable timeline for how quickly a drive will fail. A health percentage is based on SMART warnings and may not decrease steadily; the drive could run for years or fail tomorrow. I wouldn’t use it for anything important unless you have a current backup. Check which SMART attribute caused the 67% score, especially reallocated sectors, pending sectors, or uncorrectable errors.
One of my failing drives took several minutes just to open a folder, so severe slowdowns can be an early warning even before it completely stops working.
