Replacement drives for G-RAID USB Removable

We have several G-RAID USB Removable Dual Drive Storage System 8TB - Model 0G04069, and would like to upgrade the internal drives to increase capacity.

Is there a compatibility list somewhere for replacement drives? Or can we essentially use any SATA drives, as long as they match each other?

Also, is there a maximum drive size that these units will support?

Thanks-

There is no compatibility list but it should be able to accept just about any drive. We only tested them with HGST Ultrastar drives like what is inside it but it will likely work with others as long as they match.
