Backblaze Hard Drive Stats Q1 2020


A while back I wrote an article on Backing up data which seemed to attract a fair amount of interest. One of the things that was highlighted was the reliability of hard drives.

Of course the reliability of the internal disc drives can vary, fortunately Backblaze who obviously use a vast number of drives keep a regular report on hard drive reliability for both manufacturers and disk models/sizes.

The stats for Q1 2020 are now out on the Backblaze site, it does seem that the drives continue to improve in reliability.

The Annualized Failure Rate (AFR) for Q1 2020 was 1.07%. That is the lowest AFR for any quarter since we started keeping track in 2013.

The actual failure rate varies from 0% to 1.4% depending on the model so well worth having read before you purchase.
