I bought wd element 1 tb 2 months ago and its working nice on my pc, flash tv player and it works great. I recommend this because it is cheaper than wd ultra 1tb as I also have wd ultra but I don’t have usb 3.0 so both the devices wd element and wd ultra works almost same transfer rate of 29 to 35 mbps max.
I recommend this one if you don’t have 3.0 port .and if you have then wd ultra works great in usb 3.0 , I tested in friends laptop that has 3.0 port which gives speed of 50 to 60 mbps in wd ultra.
