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).
