The hard drive data is also available to download from Backblaze for anyone who wishes to analyse the figures for themselves. However, Backblaze cautions that some of the drives in the table have a fairly wide confidence interval (greater than 0.5) which implies that there is not enough data about that model of drive's performance to have a reasonable level of confidence in the AFR listed, either because the drives are too new or there are too few of that model deployed.īackblaze will be disclosing the annual failure rates for its SSD drives in a separate post sometime in the next few weeks. 11-nines data durability? Mmmm, that sounds good. If youve backed up a lot of data, you can have Backblaze put your restored files on either a flash drive or a USB hard drive for a fee. Backblaze, long a champion of home-grown hardware, succumbs to the lure of commodity servers.

Is hard drive reliability improving? Annual failure rate from Backblaze comes in at its lowest yet.

2021 in storage: We waited for a flash price revolution that never came.

At the end of 2020, the comparable figure was 1.54 per cent and a year earlier the figure stood at 1.62 per cent. These also turned out to be the oldest in the Backblaze inventory, with an average age of over 80 months.Īccording to Backblaze, the lifetime AFR for all the drives in the table is 1.4 per cent, and continues to go down year after year. fail more often as they ageīackblaze found that the drive model exhibiting the lowest failure rate was a 6TB Seagate drive (model ST6000DX000), with an annualised failure rate (AFR) of just 0.11 per cent. I would expect the larger capacity drives to.

I thank Backblaze for offering free access to hard-drive SMART data. Of that figure, 409 drives were also excluded because they were used for evaluation or Backblaze did not have at least 60 examples of that model, leaving a total of 202,759 hard drives. Due to this goal of reliable design, any data set that records hard drive failures. These included various models sourced from all four major vendors: HGST, Seagate, Toshiba, and WDC. The report leaves out boot drives (which are SSDs) and focuses on Backblaze's data drives, of which the firm had 203,168 under management as of December 31, 2021. Cloud storage and backup provider Backblaze has released a comprehensive report detailing reliability statistics for the hard drives it operated during the whole of 2021, with an interesting finding on its older kit.
