Backblaze<\/a> <\/strong>has released its hard drive reliability statistics for Q4 2017.<\/p>\n

Backblaze, which provides backup solutions, compared hard drives used in its operations – from Seagate, Western Digital, Toshiba, and HGST – for the report.<\/p>\n

Reliability was measured as an annualised failure rate, calculated using the number of drive failures relative to the number of drives.<\/p>\n

Backblaze recorded the failure rates of its hard drives from 1 October to 31 December 2017, along with the real annual failure rate for each drive.<\/p>\n

Throughout 2017, the company swapped out its 2TB, 3TB, and 4TB drives with 10TB, 12TB, and 14TB drives.<\/p>\n

Backblaze added 25,746 drives and retired 6,442 drives in 2017, gaining an additional 211 petabytes of storage capacity during the period.<\/p>\n
