The table below covers what happened just in 2018. For our evaluation we remove from consideration those drives that were used for testing purposes and those drive models for which we did not have at least 45 drives (see why below). 2018 Hard Drive Failure Rates: What 100,000+ Hard Drives Tell UsĪt the end of 2018 Backblaze was monitoring 104,954 hard drives used to store data. Along the way we’ll share observations and insights on the data presented and we look forward to you doing the same in the comments. In addition, we’ll take a look at the new hard drive models we’ve added in 2018 including our 12 TB HGST and 14 TB Toshiba drives. This review looks at the hard drive failure rates for the data drive models in operation in our data centers. Of that number, there were 1,965 boot drives and 104,954 data drives. We hope you have enjoyed reading our reports and we look forward to publishing them for as long as people find them useful.Īs of December 31, 2018, we had 106,919 spinning hard drives. From the beginning, the idea was to share our experience and use our data to shine a light on the otherwise opaque world of hard disk drives.
We titled that report “What Hard Drive Should I Buy.” In hindsight, that might have been a bit of an overreach, but we were publishing data that was basically non-existent otherwise.Many people like our reports, some don’t, and some really don’t - and that’s fine. We published our first “Hard Drive Stats” report just over 5 years ago on January 21, 2014.
