Another thing to keep in mind is that the greatest failure rate occurs in the long tails: during the first year of use and after the fifth. In net hours, a hard disk has a useful life of 20,000 hours, meaning that if you leave it turned on constantly, it will last a bit longer than two years. Thus, the best way to measure this is by number of hours in use. Although each manufacturer claims a different lifespan for its products, on average a hard drive usually lives for between 5 and 7 years, although this depends on how you use it: it’s not the same thing to use it a few hours a day as to keep it switched on for very long stretches of time. To check the number of operational hours left in your drive, there are programs such as CrystalDiskInfo.įor magnetic HDD discs, there are several related studies that pinpoint certain key periods in the life of your device. Although there are exceptions to every rule, you have to keep in mind that a hard drive has a limited lifespan, meaning it’s worth your time to crunch the numbers to see if your unit has lived out the useful phase of its life cycle. Your hard drives are your adoptive children that you need to care for meticulously for the sake of your saved data.
