Question

Is it possible to expand the storage capacity of the NX-G30 series?
Similarly, is it possible to expand the memory?

Answer

Storage

There is no slot for expansion storage.
The storage of the main unit is on-board eMMC, so the capacity cannot be changed.
Storage can be expanded by using devices that can be connected to USB.
The USB specification is USB 3.0, so faster/larger capacity commercially available products can be widely used.

Memory

There is no slot for expansion memory.
The memory of the main unit is on-board, so the capacity cannot be changed.
