Backblaze is an online backup & data backup service which uses 25,000 hard drives for its online backup service. Today, Backblaze revealed some data about which hard-disk drive manufacturers are the most reliable. The company mainly uses Seagate, Hitachi, and Western Digital. They also have few Toshiba and Samsung drives, but not enough for analysis.


The Hitachi GST Deskstar (7K2000, 5K3000, and 7K3000) had the lowest annual failure rates, from 0.9% to 1.1%. The Seagate Barracuda Green had a 120% annual failure rate (an average age of 0.8 years). The other Seagate drives had failure rates between 3.8% and 25.4%.

Great post! I always hated Seagate and preferred Western Digital just because of their reliability but I didn't know Hitachi was the top storage brand to get I always thought it was just a generic hard drive that would last you a good 6 months.


I find it funny they didn't add Maxtor to the chart but I suppose there is no need for it since they have a bad reputation of failing on you on day 1!
