I think the 1-3TB Seagate drives are garbage. Out of 6 drives I replaced all
under warranty due to bad sectors, 2 of them were replaced twice! As the
replacements failed out of warranty they were replaced with 3-4TB HGST drives
and I've had no problems ever since. My workload was just a daily backup store,
so they sat there idling about 22 hours a day.
I hear the 4+TB Seagate drives are much better quality but I have no experience
with them.
