It mentions on the horrendous failure rates of Seagate 3TB drives. I can personally confirm such thing, as my Seagate 3TB drive choked and started to die out on me. The drive technically still works... but it's having major issues trying to read random spots on the drive. It's not even half filled and yet the drive is running like a half-dead entity. After looking through Backblaze's articles, I noticed that the same model was used there and it had a horrible failure rate too.
What baffles me is how two big hard drive companies, Seagate and Western Digital, could produce terrible or mediocre drives after they've gobbled up Samsung's HD division and Hitachi's GST division. I hastily rushed out to buy a HGST 4TB drive (too big since I could personally live with 2TB) after seeing that I could buy one locally. So far, so good. But only time will tell if I end up on the short end of the stick again. (My fingers are crossed)
