Backblaze, one of many main cloud storage and backup corporations, has simply launched information on its exhausting drive failure charges all through 2020, revealing which fashions fared higher than others.
As famous by DPReview, Backblaze stories that 39,792 exhausting drives have been added to its assortment in 2020 and by the top of the yr, the variety of drives underneath its administration reached a complete of 165,530. Out of these, 3,000 have been boot drives and the remainder of the 162,530 have been exhausting drives. For this report, the corporate omitted 231 exhausting drives in its analysis as they have been used for testing or if the corporate didn’t have no less than 60 drives of a sure mannequin.

Considerably unexpectedly, for drive fashions with over 250,000 drive days over the course of 2020, the Seagate 6TB drive (mannequin ST6000DX000) led the best way with a 0.23% annualized failure fee (AFR) regardless of it being the oldest mannequin of all of the drives listed on the desk.
AFR refers back to the estimated chance of a tough drive failure throughout a full yr of use. Whereas there are different drives that will present a decrease failure fee, similar to Toshiba, the variety of drives examined was too low or the period of time they’ve been energetic was too brief to imagine the AFR could be constant over a bigger variety of drives. That stated, Backblaze has excessive hopes.
“The brand new Toshiba 14TB drive (mannequin: MG07ACA14TA) and the brand new Toshiba 16TB (mannequin: MG08ACA16TEY) have been launched to our information facilities in 2020 and they’re placing up zeros, as in zero failures,” the corporate writes. “Whereas every drive mannequin has solely been put in for about two months, they’re off to an awesome begin.”
Shut runners as much as Seagate have been two HGST 4TB drives (fashions HMS5C4040ALE640 and HMS5C4040BLE640) with 0.27% AFR, adopted by the 8TB drive (mannequin HUH728080ALE600) at 0.29% AFR, and the 12TB drive (mannequin HUH721212ALE600) at 0.31% AFR. An enchancment in comparison with the yr prior, the AFR for the entire fashions included within the 2020 report was 0.93% which was lower than half the AFR for 2019 which stood at 1.89%.
So whereas Seagate led the best way, nearly everybody noticed marked enhancements.
Backblaze describes the notable enchancment of AFR throughout the board as “a bunch effort.” On one hand, older drives as a bunch — which consists of 4TB, 6TB, 8TB, and 10TB capability drives — improved in 2020 by going from 1.35% AFR within the yr previous to 0.96% AFR. However, 30,000 bigger drives have been added to the record — of capacities 14TB, 16TB, and 18TB — and as a bunch, they too improved to attain 0.89% AFR. Total, whatever the drive capability or its age, the enhancements have been seen all through your entire vary of various exhausting drive fashions in 2020.
Backblaze set a aim at first of 2020 to diversify the drive fashions it supplied, which got here in helpful afterward when COVID-19 started affecting the world financial system and consequently the provision chain. This explicit tactic helped the corporate to navigate the market wants and limitations throughout a world pandemic. Though such excessive implications, like these skilled as a result of world pandemic, couldn’t have been predicted, Backblaze had already gone via a provide chain disruption in 2011 when extreme flooding affected Thailand. Since then, explicit consideration was paid to enhancing provide methods.
In case you are concerned with deep diving into the entire information collected, you may go to all earlier Backblaze stories, starting from 2013, on their statistics page. Whereas it won’t look like one thing a non-Backblaze person could be concerned with, these failure fee statistics are very helpful in figuring out which drives to spend money on for house or workplace use, particularly for photographers who frequently need to increase storage so as to accommodate rising picture libraries.
