The Seagate drives do seem to be improving in reliability though. The higher capacity Seagate drives which I presume are newer models have better failure rate numbers than the lower capacity drives. The 4 and 6TB drives seem to have reasonable failure rates compared to the other manufactures - only HGST is better than Seagate for the 4TB and Seagate 6TB drive has a lower failure rate than the HGST 8TB. FOr >4TB drives the Seagate 6TB has the lowest failure rate.
6TB 1.89%
4TB 2.19/2.99% (depending on model)
3TB 5.1/28.34% (depending on model)
2TB 10.1%
1.5TB 10.16%/23.86% (depending on model)
