i use a couple big Seagate usb 3 drives because they are so cheap in price. I've been running one for two years with no issue and the other for 1 year with no issue.
However, Western Digital is better. For me, these cheap seagate drives seem to be fine for storing emulation stuff, like roms, LB, emulators, media.
What you can also do, and what I did with one of my Seagate usb3 expansion drives, is crack open the case and install the bare drive internally for an internal sata cable connection. It's much better than the usb3 connection. I do keep one drive connected by usb 3 for portability, but if you don't need the portability, just crack it open (youtube videos) and install it internally. That would be my advice. Oddly, it's cheaper to buy the entire external seagate usb 3 drive than to buy a seagate bare drive.
