Their failure data matches almost exactly ours, except we purchased our drives in Q1-Q4 of 2013 instead of 2012.
Seagate has since updated this drive model, the part number has changed, along with serial number. We do not believe these exhibit as high failure rate as the earlier ones, but do not have data to correlate this.
Today, we still have some of these drives in production, well quite a few after a visit to warranty replacement, but these are mostly RAID5 arrays, and almost always there is a toshiba or hitachi drive or two in the mix (yes, you can mix brands & models in a software raid!). Failure rates has plummeted, there's only a couple failing each month on average at this time. We are largely now running on other than ST3000DM001 drives (Toshiba, Hitachi, and 8TB SMR Seagates)
