The Nintendo Switch 2 is here, and so you might be in the market for a microSD card to store more games. While all microSD cards look the same, only microSD Express cards will work on the Switch 2 for storing and playing games. Walmart’s Onn label is a beacon of light, as its microSD Express cards are significantly cheaper than the competition, with its 512GB model costing $65.88 when it’s in stock. Thankfully, since the Switch 2 has 256GB of built-in storage, you most likely won’t need a microSD Express card immediately upon receiving your console. TeamGroup has announced a microSD Express card, but it isn’t available to purchase yet.
