I recently purchased a 4tb my cloud. Its all hooked up running good. I filled it up fast with movies and such so i am looking to purchase a usb 3.0 external drive to connect to expansion port. What drives are recommended usb powered or ac powered drives? Also am I limited to a 4tb size drive or can I use a 6tb my book Thank you
Hi there and welcome to the WD community.
You can use either or, its more of a matter of preference for you, i have personally tried Mobile drives as well as ac powered drives and they have work with my unit. I hope this helps you out.
