I really only care about price now-a-days. Every hard drive will fail one day. Keep good backups and it really doesn't matter. Western Digital used to do it for me. Before that, Maxtor was my goto. I started buying Seagate about 7 years ago because they were the cheapest I could find, and have consistently remained that way. As my digital needs have expanded, I've accumulated nearly 40TB worth of Seagate drives. Couple of 2's, two of the infamous 3's, five 4's, and just got a new external 8TB.
Between all of them, not a single one of them has failed me yet. I've had some corruption issues, but I suspect that was due to the way I was connecting the drives to my PC, through a powered USB hub with a flakey power adapter attached to a single USB 2.0 port. The data was easily recovered, and I don't connect them that way anymore and haven't had the issue since.
I did purchase one 3TB WD drive in this time frame because it was the cheapest when I needed it, but after one year, it started getting corrosion on it's board. I successfully cleaned it up and got my data off of it, but the corrosion came back and it's dead now.
The only non Seagate that I'm running now is a PNY SSD for my OS (again, the cheapest at the time I bought it).
