Nintendo's Switch 2 handheld gaming console is out in the wild, and if you didn't manage to snag some extra storage for your console before its release, here are some handy links for where to pick one up now. During the Amazon Prime Big Deals Day sales events, you may be able to find one of the best microSD Express cards for the Switch 2 for less.
The Nintendo Switch 2 comes with 256GB of built-in storage, but if you want to add extra storage to your handheld console so that you can store more installed games, you're going to need to invest in the latest microSD Express storage technology, as the Nintendo Switch 2 is only compatible with microSD Express cards.
The Nintendo Switch 2 will support microSD Express cards with a capacity of up to 2TB, which should be more than enough to store a large number of games, should you want them all downloaded and preinstalled for on-the-go gaming. Only the Switch 2 will be able to fully utilize the increased performance of the microSD Express card. If you use the card in the original Switch, it will perform at the same level as a standard microSD card. So don't buy one thinking you can increase the performance of your original Switch console.
There will be licensed microSD Express cards for the Nintendo Switch 2, featuring a Nintendo logo, such as the Mario "M," as were available for the original Switch. These microSD Express cards will be available for purchase directly from the Nintendo shop when they become available on June 5, 2025. Currently, prices are not listed for these licensed editions of Samsung's microSD Express 256GB cards. These cards should not have any performance advantage over standard models; it's just a branding decision. As such, one way to save a few bucks is to purchase a third-party, unlicensed microSD Express card from various other manufacturers and retailers.
