I had 8 of the 14tb exos, 5 of them failed over a 2yr period. I keep falling for the cheap seagate pricing but they consistently die on me every single time. On the flip side, Toshiba and HGST are absolutely rock solid.
How did these drives arrive in shipping? That makes a huge difference no matter who makes the drive...Ouch. I Got a 10tb variant that showed smart errors a year into running it. Told myself not to buy it, knew better, but still did anyways...Let me down as expected.
