One Billion Drive Hours and Counting: Q1 2016 Hard Drive Stats

One Billion Drive Hours and Counting: Q1 2016 Hard Drive Stats. Andy Klein. Backblaze. May 17, 2016.
     Backblaze reports statistics for the first quarter of 2016 on 61,590 operational hard drives used to store encrypted customer data in our data center. The hard drives in the data center, past and present, totaled over one billion hours in operation to date.The data in these hard drive reports has been collected since April 10, 2013. The website shows the statistical reports of the drive operations and failures every year since then. The report shows the drives (and drive models) by various manufacturers, the number in service, the time in service, and failure rates. The drives in the data center come from four manufacturers, most of them are from HGST and Seagate. Notes:
  • The overall Annual Failure Rate of 1.84% is the lowest quarterly number we’ve ever seen.
  • The Seagate 4TB drive leads in “hours in service” 
  • The early HGST drives, especially the 2- and 3TB drives, have lasted a long time and have provided excellent service over the past several years.
  • HGST has the most hours in service
