Long answer: In 2014, cloud backup company Backblaze started posting statistics on the failure rate of over 27,000 hard drives and their respective brands. We don’t have enough definitive data on Samsung or Toshiba to make a conclusion about them. Short answer: HGST (rebranded name for Hitachi) drives generally last longer than Seagate and Western Digital. Which hard drive brands last the longest? All of the discussion below, unless otherwise noted, refers to standard magnetic disk drives, not solid state drives or hybrid drives. These factors and many more can affect the lifespan of a hard drive. Is it frequently shaken, vibrated, or bumped?.What do you use it for? Running applications, viewing media, or storage?.These drives are also kept in controlled environments and don’t undergo the same conditions as, say, your laptop drive. Many of the hard drives tested do not fail at all. Long answer: A handful of studies on the lifespan of hard drives might give you some clearer indication, but they still aren’t very helpful. Short answer: That being said, if you just want a quick rule of thumb for how long you can expect the hard drive in your laptop should last, we’d say you should be prepared for disk failure after three years of use. Hard drive failure is unpredictable, so answering the question of how long hard drives last will inherently comes with a lot of caveats.
