Online storage serviceBackblazeAnnounced the latest September 2014 update of "HDD Reliability Data" calculated from the total of about 200 types of data used for its services, totaling about 35,000 units. from beforeBias of fragility depending on manufacturers and modelsAlthough it was clear, that tendency seems not improved much.

This is a graph that shows which manufacturer's HDD is reliable with a single shot. The gray bar graph shows the failure / error incidence rate for the whole year of 2013, and the colored bar chart shows the error occurrence rate that occurred by June 2014.SeagateBroken heart and Hitachi (HGST) The degree of stability is obvious at a glance.


In Seagate's 3 TB model the error rate increased from 9% to 15%Western DigitalThe 3 TB model also said that the error rate increased from 4% to 7%. As a general comment, all Hitachi HDD, 4 TB model of Seagate, 1 TB model of Western Digital are concluded to be reliable.

Surprisingly, Seagate's HDD seems to have almost the same rate of failure even if it is more than twice the price for general consumers, and on the data it is slightly higher for ordinary consumer HDD It was difficult to break down.

The tendency of the problem indicated by this bar graph is almost the same as the data of January 2014, and it is reliable as a graph showing broken back, Backblaze says.

This table shows the breakdown rate by manufacturer / model number. "Number of Drives" is the number of HDDs in use, "Averatge Age in Years" is the average age of use and "Annual Failure Rate" is a failure / error occurrence rate of full year, Seagate's 3 TB model "ST 3000 DM 001" The failure / error occurrence rate is 15.7% with the use for about 2 years, the 1.5 TB model "ST31500341AS" has a fault / error occurrence rate of 24.9%, and the low reliability is revealed low. In addition, "ST31500341AS" has a small number of samples as 365,In January 2014 survey recorded an error rate of 25.4%It was a model I was doing.
