Cloud backup business Backblaze: Failure rates fell for high-capacity hard drives

Just 139 out of 10,000 12TB Seagate drives fail a year, and Western Digital's HGST brand has an even better rate of 51 in 10,000, according to cloud backup service provider Backblaze, which has 104,778 drives spinning in its data centre.

It's not an exhaustive study; the firm listed just four brands in its estate, with models ranging from older ones with 3TB of capacity to newer 12TB drives and some 14TB drives from Toshiba. However, it does provide some data points for the curious.

It has 31,146 Seagate 12TB disks and 1,278 HGST 12TB spinners. The backup firm claimed the best ever drives it purchased were 45 Toshiba 5TB units, none of which had failed. But of course the sample size of 45 is too small for a valid annualised failure rate (AFR).

[...] The next best is a Seagate 10TB drive with a 0.33 per cent AFR from a population of 1,210 drives. That means 33 out of a batch of 10,000 would fail each year.

    Except that that's a huge pain in the ass and a waste of time. How the hell is that immaterial, even assuming you can get the manufacturer to honor their warranty?
