Those 3TB Seagate drives are literally the worst in the business. The 2TB and 4TB are pretty good (roughly on par or better than competitors according to the backblaze reports) but those 3TB drives were utter shit for some reason, ~20% year over year failure rates. Some retailers have even started to sell the 3TB Seagate drives at almost the same price as the 2TB ones. Probably the only way to get rid of them.

Well that's reassuring... I just built my home NAS. 3 3TB WD Reds and 3 3TB Seagate NAS drives. Two of the Seagates were DOA so I got them replaced. I ran full hard drive tests on them without problems but now I'm extra paranoid.

  That's what RAID is for, just make sure you scrub it often enough to catch any potential failure. If you're ever looking for replacements, those 4 TB Seagates are hard to beat without paying enterprise-level prices, despite how much of a turn-off the high failure rate on their 3TB drives may be.

Safe to say the 3 TB drives are 4 TB drives that failed one manufacturing test or another.

Please remember that back blaze was cracking open external hard drives in that case. Also, at the time, one of the large HDD manufacturers lost their main build plants. So who knows where Seagate got their components from in that 1-2 year period. Given the fact that Seagate's 4TB hard drives are considered by back blaze as the best HDDs, I find it a little odd that everyone assumes that manufacturing issues 4 years ago affect drives being built today. Also, back blaze statistics only apply if you're operating at back blaze's scale. If you're making a home NAS you would have to be _incredibly_ unlucky to hit a bad drive as quickly as back blaze did. I

  I've anecdotally experienced very high failure rates on them too, had 3/6 fail in about 5 years. And many other anecdotal reports indicate similarly bad results. Maybe not as bad as Backblaze but pretty damn bad. I absolutely agree though, the 4TB are a great improvement, you can't beat them for reliability unless you're really willing to pay for it. I've chosen them for my personal NAS and some servers even with great results so far.
