BASEQI Aluminum MicroSD Adapter for Surface Book 1-3

Turn a MicroSD Card into a Permanent Expandable Storage for Surface Book

If you are looking to expand the storage of your Surface Book, the only thing you can do is using the SD card slot. Since it is a full-sized SD card slot, you will need a full-sized SD card or SD card adapter. However the depth of the slot is about half-length of the card, so it’s not a good idea to use the full-sized SD card as a permanent solution to expand the storage.

Fortunately, there is a MicroSD Adapter made by BASEQI that is firm and nicely fit the Microsoft Surface Book card slot without sticking out. With that said, you can now use any microSD card to expand the storage on your Surface Book. It has the same color and aluminum designed just like the Surface Book’s chassis.
