3TB Seagate Hard Drives Have 43% Failure Rate, According to Backblaze

Cloud storage provider Backblaze, in its 2014 ‘Hard Drive Annual Failure Rate’ graph, reports that the 3TB Seagate Barracuda drives it used for its storage service had a 43.1% failure rate over 2014. Other Seagate models also performed badly, with the 1.5TB Barracuda 7200.11 failing 23.8% of the time.

It must be noted that Backblaze exposed the drives to heavy stress, using them 24/7 to support user data. Seagate’s drives, designed purely to serve as home external storage devices, are not expected to handle more than eight hours use a day, nor be used as part of a massive vibrating enclosure, so it is baffling why Backblaze would continue to use Barracuda HHDs for a task they are so ill-suited to.

Not every hard drive manufacturer fared as badly as Seagate, though. HGST drives in particular proved to be very reliable under heavy use, with its 2 to 4TB drives boasting only a 2.3% rate of failure for the year, and the 2TB 7K2000 model leading the pack with a 1.1% failure rate.
