The Leica T camera’s internal/built-in memory storage is just a regular micro SD memory card that can easily be replaced/upgraded if you take off the plastic cover on the side where you put the external SD memory card. Here are some pictures sent in by @depotmsa – he successfully replaced the internal 16 GB card with a new 128 GB micro SD class 10 memory card that now has much faster read/write speeds (I wonder how many other Leica cameras are designed that way):
