Good harddrive

Storage Size: 2TB

If you're a Mac user you'll need to reformat it if you use this harddrive for media between devices. If you don't have one already, purchase a USB-C hub because the harddrive won't fit any ports in the newer macbook air. A suggestion is the belkin USB-C multimedia hub which has multiple ports.

Good value

Storage Size: 2TB

Bought this hard drive to use as a backup for my laptop hard drive and another external drive, it's big enough I can fit all that and more on it, easy to plug and play and seems reliable so far.
