Interesting, I built a home FreeNAS a few years ago, with Seagate 3TB drives, 7200.12 iirc, and saw 3 of them (out of 12) fail well under 2 years... at this point, I've had so many issues, it's pretty much sitting there. I put 4x4tb WD reds into my older Synology NAS and have been using that without issue.
