Over 2021, Backblaze added 40,460 hard drives to its pool of drives, making a total of 206,928 drives in total. While it might not seem like something a non-Backblaze user would be interested in, these failure rate statistics are very useful in determining which drives to invest in for home or office use, especially for photographers who regularly have to expand storage in order to accommodate growing image libraries. This offers an interesting insight into drive reliability. If you are interested in deep diving into all of the data collected, you can visit all previous Backblaze reports, ranging from 2013, on their statistics page. Since then, particular attention was paid to improving supply strategies. Although such extreme implications, like those experienced due to the global pandemic, couldn’t have been predicted, Backblaze had already gone through a supply chain disruption in 2011 when severe flooding affected Thailand. The stats for Q1 2020 are now out on the Backblaze site, it does seem that the drives continue to improve in reliability. This particular tactic helped the company to navigate the market needs and limitations during a global pandemic. According to these data, the annual failure rate is 1.07, and according to the company it is the lowest they have had since 2013, and is in fact significantly. For years, the online backup service Backblaze has been publishing its hard drive failure statistics, and the company has now released the numbers for 2019. Overall, regardless of the drive capacity or its age, the improvements were visible throughout the entire range of different hard drive models in 2020.īackblaze set a goal at the start of 2020 to diversify the drive models it offered, which came in useful later on when COVID-19 began affecting the world economy and consequently the supply chain. On the other hand, 30,000 larger drives were added to the list - of capacities 14TB, 16TB, and 18TB - and as a group, they too improved to achieve 0.89% AFR. So while Seagate led the way, just about everyone saw marked improvements.īackblaze describes the notable improvement of AFR across the board as “a group effort.” On one hand, older drives as a group - which consists of 4TB, 6TB, 8TB, and 10TB capacity drives - improved in 2020 by going from 1.35% AFR in the year prior to 0.96% AFR. An improvement compared to the year prior, the AFR for all of the models included in the 2020 report was 0.93% which was less than half the AFR for 2019 which stood at 1.89%. “While each drive model has only been installed for about two months, they are off to a great start.”Ĭlose runners up to Seagate were two HGST 4TB drives (models HMS5C4040ALE640 and HMS5C4040BLE640) with 0.27% AFR, followed by the 8TB drive (model HUH728080ALE600) at 0.29% AFR, and the 12TB drive (model HUH721212ALE600) at 0.31% AFR. According to Backblaze’s data, the company added 39,792 hard drives to its collection 2020, bringing the total to 165,530 drives. As a consumer – forget the reviewer bit – I just don't yet trust drives larger than 2TB for mainstream or production use.“The new Toshiba 14TB drive (model: MG07ACA14TA) and the new Toshiba 16TB (model: MG08ACA16TEY) were introduced to our data centers in 2020 and they are putting up zeros, as in zero failures,” the company writes. I can deal with losing 2TB of data (and it's easier to back up), but losing 4TB is just too much. As of March 31, 2020, Backblaze had 132,339 spinning hard drives in their cloud storage ecosystem spread across four data centers. Number of Hard Drives by Model at Backblazeįor personal use, I tend to stick to 2TB WD Black HDDs and have not yet gone over 2TB in capacity. Smaller drives – like 1TB WD devices – have proven more stable. Backblazes Q3 2020 hard drive stats: As of September 30, 2020, Backblaze had 153,727 spinning hard drives in our cloud storage ecosystem spread across four data centers. WD 3TB drives aren't immune to worsened lifespan, though, and have also jumped from 4% to 7% in annual failures. As of September 30, 2020, Backblaze had 153,727 spinning hard drives in our cloud storage ecosystem spread across four data centers. The company noted a slight increase in quarterly AFR. The latest report reinforces earlier data that Seagate has some of the poorest longterm endurance of all tested devices, with 3TB drives climbing to a 15% annual failure rate (from 9% at the time of last reporting). Bottom line: Backblaze has published the latest reliability figures for its data drives (HDDs) and boot drives (SSDs and HDDs) for Q2 2021. The reporting period is from 1 April 2013 through 30 June 2020. In the first test performed in 2021, Backblaze did an observation on 171,919 hard drives spread across four data centers. BackBlaze just reported its annual failure rate for 34,881 drives that house 100 petabytes of data (that's 100,000,000 gigabytes). The table below shows the reliability of hard drive models Backblaze had in service as of 30 June 2020.
