Frequently Asked Questions
What's the fastest SD card the Switch can use?
The Nintendo Switch uses a UHS-I interface, maxing out around 100 MB/s read speed. Buying a UHS-II card won't hurt, but you won't get faster speeds than a good UHS-I card provides.
How many Switch games fit on a 256GB card?
Approximately 15-25 games depending on size. Indie titles average 1-4GB while AAA ports can be 10-30GB. A 256GB card is a comfortable middle ground for most Switch owners.
Can I use the same SD card on Switch and Switch 2?
microSD cards are physically compatible with both consoles. Game saves are stored on internal memory, but downloaded games on the card may need to be redownloaded on a new console due to encryption.
