How to insert a second SSD?
Do all CHUWI LapBooK Pro 14.1 all have a dedicated slot?

Chuwi LapBook Pro with 8GB of Ram and 256GB SSD does not have a second slot for an SSD volume, to expand the storage you will need to remove the original SSD

Thanks for the information! I thought the second slot was hidden somewhere.
