Can a second 2 bay MyCloud EX be added... or

… would I need another MyCloud account?

I have 2 4Tb WD Red drives that are in need of a NAS enclosure.

I already have a MyCloud EX Ultra with 2 x 4TB drives, which is all working fine. I am curious, if I purchased another MyCloud EX Ultra 2 bay enclosure, would I be able to run another NAS drive on the same MyCloud account, or would I need to set up a new separate MyCloud account.

Apologies for the noob questions.
Thanks

Not sure about the WD Cloud apps.

In terms of running two NAS box’s locally on a network; it is no problem as long as you have unique device names.
