My book World edition

i have a NAS WD my book world edition with 2 disks 1 TB each configurated in raid 1

could it possible to change both disks? I want replace them with two other of the 3TB capacity.

How can i do? What kind of disk i have to use?

thank you

Hi, as far as I know you cannot upgrade the capacity, it’s supposed to be limited by the controller. Check if the link below helps.
