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.”

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.
