Backblaze Hard Drive Stats for 2018

Backblaze has released a year’s worth of hard drive statistics for those who are convinced certain brands fare considerably better than others. While the backup company’s latest charts do bolster the reputation of certain drives (e.g., HGST/Hitachi), 2018’s annualized failure rate was only 1.25%, the lowest the company has ever recorded.

As of December 31, 2018, we had 106,919 spinning hard drives. Of that number, there were 1,965 boot drives and 104,954 data drives. This review looks at the hard drive failure rates for the data drive models in operation in our data centers. 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. 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.
