Which HDDs have failed the most from WD, HGST, Seagate and Toshiba in 2022?

Hard drives are considered fairly reliable data storage systems and although as a general rule they tend to last for many years, it must be borne in mind that the failure rate depends a lot on the model. As we could see in the failure rates of Q2 2022, there were models that failed 5% and others that barely reached 1%. Now that we are in 2023, backblaze has updated these figures thus indicating the hard drive failure rates by 2022.

When Backblaze tested hard drives in August 2022, we could see that Seagate was one of the brands with the most failures. In fact, in the statistics of that news, we could see that the failure rate was led by the Seagate ST14000NM0138 of 14TB with a 5.64%. After this we had a Seagate ST12000NM007 of 12TB with a 5.01% and a Seagate ST4000DM000 of 4TB with a 3.42%. But of course, the figures were given per quarter, because if we went to the section with the highest failure rate in the entire useful life of the discs, the hgst of 8TB HUH728080ALE604 led with a 6.26%.

After making other cuts, in the end a total of 230,921 HDD throughout 2022. Of these we can summarize that the ones with the most failures in 2022 are:

  • Seagate ST14000NM0138 14TB with a failure rate of 5.70%.
  • HGST HUH728080ALE604 8TB with a failure rate of 5.27%.
