The Seagates you are proposing as replacements are using. Your five-year-old drive is using ten-year-old technology at best, but that technology level is cheap, reliable, and fast enough to perform more than adequately as a Time Machine drive. Given the rate of advancement in computer technology a five-year-old drive is antiquated and as far as Apple is concerned a seven-year-old drive is, by corporate policy, obsolete. Every once in a while I dig through the stack and discard one or two to recover some space in my junk drawer. I have some drives that are still functional and over 10 years old, but I never use them because they are too small and too slow by today's standards to be useful in my current system. One apple rep and BH rep said with spinning drive cause spinning and so fragile to wear they would replace every 5-6 years regardless, I think many subscribe to that. then you would keep them even in 5, years old, 10 years old 12 years old? There is no random cut-off date even if spinning drive? If a couple of my older drives pass test. That leaves volume repair and not only has Disk Utility improved on its ability to do volume repairs they have become so infrequent that many no longer bother to keep the various repair facilities up-to-date and unless they are up-to-date they can actually do more harm than good. Add to that for years macOS has quietly been doing its own optimization in the background. Just install it, set your preferences, and forget it until a warning arises.ĭefragmentation still can improve the performance of an HD formatted HFS+, but APFS is intentionally fragmented and arguably have a deleterious effect on the lifespan of SSDs. I forget it is running until it warns me of an impending failure. You can set the checking interval and specify the actions to take if there is problem detected. DriveDX's entire process takes a few seconds at most and has no discernable impact on system performance.

and NVME trends are the most reliable predictor of impending drive failure and those values include and improve on the same information that you would look for in a full scan of the drive that could take hours on a big drive.
or NVME data stored in registers on the drive and analyzes the results. It does not scan the drives per se, it simply reads the S.M.A.R.T. I have DriveDX set to run every four hours. (I initially set it to send me a summary report every 48 hours, but the report was boring and I don't need any more email, so I canceled that.) or NVME values on each of my drives every 4 hours and report immediately if the health of a drive falls below my preset comfort level. FWIW, I have DriveDX set to routinely check the S.M.A.R.T. It never actually failed but I had plenty of time to find and install a replacement drive in the same enclosure. Within a few days of installing DriveDX on it flagged one of my HDs (a 3-year-old industrial grade Seagate) as an impending failure. values of hard drives and NVME statistics on SSDs, even those connected via technologies like USB that theoretically do not support S.M.A.R.T., to provide adequate warning of impending drive failure to keep your data safe.

DriveDX, Drive Scope, and TechTool Pro all perform a thorough analysis of the S.M.A.R.T.
The failure rate is a standard distribution and the published MTBF (Mean Time Between Failure) is just that and no more. A drive can easily outlast the technology before failing or it could fail within minutes of being powered up the first time. The same is true of the drives you use every day. Rather than replace any drive solely because of its calendar age, I would run diagnostics on the drive every time you bring it into the house for backup and keep it as long as it passes diagnostics. Thre are a lot of factors impacting the useful lifespan of a hard drive and calendar age or time in use is relatively low on that list.
