When they did, we had a number of folks reach out because of a recent feature on STH. Header image by Denny Müller on Unsplash. This week, Backblaze released its quarterly hard drive reliability stats. We’ll be watching the Backblaze blog for upcoming stats and observations as the hard drives continue to be tested over the coming months.
This model was also the oldest, in average age, of all the drives listed. Low annualized failure rate for Seagate 6TB drive (more drive days)įor drive models with over 250,000 drive days over the course of 2020, the Seagate 6TB drive (model: ST6000DX000) led the way with a 0.23% annualized failure rate (AFR). Backblaze tested 6,0002 pieces of that WDC model and found that the AFR for this drive model was just 0.16%. Only one Western Digital drive made it onto the report, the 14TB model WUH721414ALE6L4, however it’s important to say that HGST is a Western Digital brand, so they are under the same corporate umbrella – and HGST drives have consistently been outperforming Seagate drives over many years (and this year is no exception). Backblaze has published its Q1 2020 hard drive stats, which looks at the failure rates for 129,764 hard drives from HGST, Toshiba, and Seagate (this figure excluded test drives and drive. Toshiba’s drives have been impressive, with a 14TB drive (model: MG07ACA14TA) and 16TB drive (model: MG08ACA16TEY) each delivering zeros for annualized failure rates (AFR) – though these drives had only been installed for two months by the time Backblaze’s 2020 stats were published. Most reliable hard drives from Toshiba, HGST, Western Digital The good news is, the annualized failure rate has dropped by 50% since 2019, where it stood at 1.89% compared to 2020’s 0.93%.
