The Nintendo Switch 2, like its predecessor, will use MicroSD cards for external storage. However, the new console is only compatible with MicroSD Express cards, meaning you’ll likely need to pick up a new SD card if you want to expand your storage. Here are the places you can look for MicroSD Express cards for the Nintendo Switch 2.

So saying, you probably don't have a microSD Express card, and you're definitely going to want one if you're getting a Switch 2. While all of Nintendo's games seem to be coming on real PCI Express-enabled game cartridges, it has been revealed that many third-party games will not have proper physical cartridges for their "physical" releases.

The Nintendo Switch 2 is so popular that even MicroSD cards are selling out in both online and physical stores.
