Unlike the original Switch, the Nintendo Switch 2 requires microSD Express cards for storing and playing games. While physically identical to microSD cards (aside from a small, easy-to-miss “EX” emblem etched onto the front of the card, as highlighted in the main image above), microSD Express cards are significantly faster. They advertise a 4.4x increase in transfer speeds over regular microSD cards.
That speed boost is necessary for loading Switch 2 games that have more detailed textures and larger worlds than those that are possible on the original Switch. You may not need to buy one immediately, however, unless you foresee quickly using up the Switch 2’s built-in 256GB SSD.
If you do want a microSD Express card, there are many options available. Yet, all of them boast the same speed and performance. I suggest getting the most affordable microSD Express card you can find and buying it from a brand you trust, just in case anything goes wrong with it while the warranty is still valid.
While microSD Express cards were initially very expensive — costing nearly $200 for 1TB of extra storage — prices have come down a bit for certain storage amounts. What’s more, deals occasionally drop the price of the 256GB and 512GB models below the price of some games ($35 for 256GB and $75 for 512GB are among the lowest prices we’ve seen on Amazon). The Switch 2 supports microSD Express cards up to 2TB in size, although 1TB is the largest capacity available, with some cards selling for up to $200 a pop. Walmart’s Onn model is a beacon of light even when there are no deals, as the regular cost for its 512GB model is around $84.
