In order to use a microSDXC card on the Nintendo Switch console, a system update is required.
In order to improve your gameplay experience, using a microSD card with a higher transfer speed is recommended.
High-speed microSD card guidelines:
Game save data is stored to the system memory and cannot be copied or saved to a microSD card.
Screenshots and captured gameplay videos can be moved from the system memory to a microSD card, and vice versa. Downloadable software cannot. If you want to free up space on the system memory, simply delete any saved software, and redownload it from the Nintendo eShop while a microSD card is inserted in the console.
Game save data cannot be copied to a microSD card.
We recommend using a single microSD card with your Nintendo Switch console. If you run out of space, you can copy over all the data to a larger microSD card.
