I don't have any major gripes, but I think HGST is the best, which WD bought.
And the 3.5" Toshibas derive from HGST, so I already chose it once.
I got a Toshiba one. I don't trust them though simply because they are not a dedicated storage company like WD who's sole business is computer storage more or less. Just my philosophy in buying
Micro-USB has always been a week point in external drives. Move your drive but 1 mm on the table and it gets disconnected. At least that's my experience.
So why does WD feel the need to solder on the usb controller? That's the main criticism here. Other than that, WD hard drivers are very reliable and I don't use anything else.
hmm... I move my HDD all the time nothing happens, plus I think they abandoned the micro-USB for the full USB 3 now.
