               Backblaze's 2020 Hard Drive Reliability Statistics

   Josh Centers

   For the seventh year in a row, cloud backup service Backblaze has
   [1]published its annual hard drive reliability statistics. The company
   now manages a total of 162,530 data drives. An interesting thing
   happened last year: the annualized failure rate (AFR) was cut nearly in
   half: from 1.89% in 2019 down to 0.93% in 2020. As has been true in
   past years as well, HGST drives outperformed Seagate drives, although
   it's worth noting that many of these drives are now larger than most
   consumers would be likely to purchase. Backblaze noted that it added
   over 30,000 drives in 2020 that were sized at 14 TB or larger, and they
   performed well overall, with an AFR of 0.89%, beating out the 12 TB
   drives' AFR of 0.98%.
