Backblaze Uncovers the Most Reliable Hard Drives

Backblaze, a cloud storage service that's been running hundreds of thousands of storage drives to keep an eye on reliability, has issued its latest report. ZDNet summarizes the major findings: Over 2021, Backblaze added 40,460 hard drives to its pool of drives, making a total of 206,928 drives in total. Of thee, 3,760 are boot drives and 203,168 are data drives. There's a lot of information in the report to look at, but there are two standout parts from the report:

- The oldest drive is the most reliable: 6TB Seagate drives (model: ST6000DX000) have an average age of 80.4 months (almost seven years) yet incredibly these also have the lowest annualized failure rate (AFR) of 0.11 percent.

- Newer drives are also doing really well: 16TB WDC drives (model: WUH721816ALE6L0) and 16TB Toshiba drives (model: MG08ACA16TE) were both added in 2021, and have an AFR of 0.14 and 0.91 percent, respectively.

Backblaze had also been experiencing problems with the 14TB Seagate drives (model: ST14000NM0138) in its Dell storage servers. It seems that following a firmware update the reliability of these drives has improved dramatically. Further reading: Seagate HDDs Top and Bottom Backblaze's 2021 Failure Rates Data (Tom's Hardware)
