"[...]At the moment companies have to back up their archives every five to ten years because hard-drive memory has a relatively short lifespan,” says Jingyu.
Since when hard drives die after 5-10 years? Are there some new physics laws that I'm not aware of, or what?
- eksith 13y agoI'm guessing this is with MTFB rates given by manufacturers. With continuous use, it's not that uncommon to for hard drives to reach EOL fairly quickly.
- sambeau 13y agoIt's a bit off but in the ballpark: Google's 2007 study found, based on a large field sample of drives, that actual annualized failure rates (AFRs) for individual drives ranged from 1.7% for first year drives to over 8.6% for three-year old drives http://en.wikipedia.org/wiki/Hard_disk_drive_failure http://en.wikipedia.org/wiki/Hard_disk_drive_failure Memory, of course, has other problems: http://www.ewh.ieee.org/r6/scv/rl/articles/ser-050323-talk-ref.pdf http://www.ewh.ieee.org/r6/scv/rl/articles/ser-050323-talk-r...
