![]() That's a mere four months apart from Backblaze's 2 years and six months result. It looked at 2,007 HDDs and found their average life before failures to be set at around 2 years and 10 months. Simply put, there's no way to say that "HDDs are becoming worse" from this data as there are too many unknowns.īackblaze's Annualized Failure Rates report looks relatively aligned with similar HDD failure analysis conducted by Secure Data Recovery, an HDD, SSD, and RAID data recovery company. It could also be a problem with a batch of drives, or from handling, installation, and operating conditions. This could mean that some models have a lower than expected durability and have started failing. ![]() When looking at these numbers, it's important to remember that even Seagate's failure rate means that only 2.3 out of every hundred shipped HDDs stop spinning their platters before they should.Īll in all, Backblaze ended up with an average failure rate for Q1 2023 of 1.54%, up quarter-over-quarter from 1.21% in Q4 2022 and also up year-over-year, where Q1 2022 registered a 1.22% AFR. That isn't the case for higher capacity drives, which are also more likely to have a lower running time, as is generally the case for Backblaze's storage options.īackblaze further analyzed its HDD pool by looking at average failure rates among manufacturers, with Seagate claiming a leading, average failure rate of 2.28%, while WDC claimed the least average failures with its 0.31% result. For one, Backblaze points out that all of its "small capacity" HDDs that were destined to fail already did: the company no longer utilizes 1, 1.5, 2, 3, or even 5 TB HDDs - all failures within those models are already "counted in" on Backblaze's failure rates. The second-worst drive model in Backblaze's statistics was another Seagate drive, the 14TB ST1400NM0138 drive saw an AFR of 6.23% The third worst model is HGST's 4TB HUH728080ALE604, with an annualized failure rate of 4.33%.īackblaze's results could be interpreted as meaning that bigger HDDs tend to fail less often than smaller HDDs, but there are a number of caveats here. Its 12TB Seagate ST12000NM0007 saw 2,023 failures, ending up with the greatest Average Failure Rate (AFR) at 7.46% and an average lifetime of just one year and six months. For one, we see that Seagate is the king of drive failures. (Image credit: Backblaze)īackblaze noted some trends in its evaluation, and the table itself gives us some interesting data points. Backblaze analyzed Annualized Failure Rates (AFR) on drives manufactured by HGST (7 models), Seagate (13 models), Toshiba (7 models), and WDC (3 models). ![]()
