Typically, large quantities of hard drives are susceptible to premature failures–some drives arrive from the factory dead, or fail in the first few hours of being powered on. Of note, all of these are Seagate drives, the ST10000NM0086 and ST12000NM0007, both of which are Helium drives.
Backblaze hard drive reliability 2017 pro#
SEE: Power checklist: Managing backups (Tech Pro Research)īackBlaze has added 1,240 drives with capacities of 10 TB or more this quarter.
As the currently deployed drives are relatively new, fewer drives are failing as part of the limitations of their natural lifecycle. Of those drives, only four of the 2,490 (0.59%) presently deployed failed in Q3. Only the HGST-produced 4TB drives (specifically, HDS5C4040ALE630) have an average age of more than four years. The report noted that there are several factors that led to this result, not the least of which is the average age of drives. Drives are becoming more reliableĪccording to the report, in Q3 BackBlaze experienced the lowest failure rate of hard drives ever, at 1.84%. Rather than rely exclusively on enterprise-grade hard drives, BackBlaze uses a mixture of enterprise and consumer hard drives, primarily purchasing whatever can be found cheaply.įor Q3 2017, BackBlaze added 9,599 new drives and decommissioned 6,221 drives, bringing the total to 86,529 hard drives, sourced from 17 different SKUs across all four manufacturers. Since 2013, cloud storage firm BackBlaze has published quarterly reports and raw performance data detailing the drives in their data centers.
