Online backup service Backblaze has posted its hard drive reliability statistics for 2016, based on nearly 72,000 drives and almost 23 million drive-days. At the end of last year, overall failure rates were 1.95 percent, which is down 0.52 percent from last year. The most reliable drive maker was HGST, with a failure rate of just 0.60 percent, whereas HGST’s owner Western Digital brought up the rear, with 3.88 percent of its drives dying. Backblaze uses more drives from Seagate than any other manufacturer, and while Seagate’s new 8 TB drives proved quite reliable, the company’s 4 TB drives remain problematic. Backblaze’s most heavily used Seagate 4 TB model posted an above-average failure rate of 2.77 percent, and another model stumbled in with an abysmal 13.57 percent failure rate. The moral of the story: pay close attention to manufacturer and model when buying drives.
