In February of 2016, the hard drive manufacturer Seagate was hit with a class action lawsuit regarding the poor reliability of their 3 Terabyte drives. The lawsuit brings to light the unusual amount of failures from 2012 onwards. It has found roughly only 68 percent of 3TB Seagate drives deployed in 2012 failed by early 2015. In comparison, drives from over manufacturers had a survival rate of 80 percent after 4 years. This lawsuit mainly sourced a Backblaze report on the reliability of hard drives in their server room.
If you currently are using this model, we would recommend backing it up immediately. The discrepancy between the failure rate of these models is larger than normal, so the claim that these specific drives are less reliable is credible. Hopefully Seagate has rectified this situation, and made their reliability rates a little more competitive.
