Will it actually be reliable? Seagate always seems to experience the highest failure rates while WD and HGST have the lowest. I'd like an 8TB WD Red, but I can't afford to spend ~$750-800 for two of them (one as a redundant backup).
I've been pretty lucky so far with Seagate drives. I have had four of their external hard drives - a 1TB USB 3.0 desktop model, 1TB USB 2.0 portable, 250GB USB 2.0 portable and a 3TB Barracuda and so far the only one that has failed is the 250GB. I was using it for school running all kinds of VMs off of it, got ~4 yrs of life out of it.
I've also got a WD 2TB USB 3.0 portable, WD 3TB USB 3.0 portable, WD Red 3TB, 750GB HGST and a couple of Samsung 250GB SSDs. I will probably just stick to WD or HGST in the future as those brands seem to have the best reliability.
