Where to Buy microSD Express Cards for the Nintendo Switch 2: A Simple Guide

The Nintendo Switch 2 is almost here! Set to launch on June 5, 2025, fans everywhere are getting ready to dive into the next generation of portable gaming. Pre-orders open on April 24, and many gamers are already planning what extras they’ll need. One important accessory? A microSD Express card.

If you’re thinking about picking up the Nintendo Switch 2, you should also think about expanding its storage. While the console comes with 256GB of built-in storage, that space can fill up fast once you start downloading games. That’s where microSD Express cards come in.

Why You Need a microSD Express Card for the Switch 2

The Nintendo Switch 2 uses a brand-new type of memory card: the microSD Express card. This is different from the regular microSD cards that worked with the older Switch models. Why the change? Speed. The new cards read and write data much faster, which helps games run more smoothly and reduces loading times.

The Switch 2 is only compatible with these new Express cards. That means older microSD cards won’t work the same way, and you won’t get the performance boost if you try using an Express card in your original Switch. So, if you're upgrading to the new console, you'll definitely want one of these high-speed cards to get the best experience.

What to Look For When Buying

When shopping for a microSD Express card, make sure to check for the “EX” symbol on the card or packaging. This symbol means the card supports the faster Express standard, which is required for the Switch 2.

These cards will come in different sizes, all the way up to 2TB, so you can choose how much space you need. A 256GB card will double your storage, but if you're planning to install a lot of games, you might want to consider 512GB, 1TB, or even the 2TB option.

Just keep in mind: these cards aren’t cheap. Larger ones, like the 1TB or 2TB versions, can cost hundreds of dollars.

Official vs. Unofficial Cards

Nintendo will be offering official licensed microSD Express cards, which will feature familiar logos like Mario’s “M”. These cards are made in partnership with companies like Samsung and SanDisk and are expected to be high-quality.

For example, Samsung’s licensed 256GB card is already available for preorder at stores like Walmart and Target. It’s priced around $60, which is actually a pretty good deal considering it's a special edition and offers fast speeds of up to 800MB/s.

But you don’t have to buy the official versions. Third-party cards from brands like Lexar and SanDisk are also available and may cost less. Just make sure they’re Express cards with the correct EX symbol.

Where to Buy microSD Express Cards

Right now, microSD Express cards are in high demand. Some sizes are already sold out at major retailers. Here are some of the best places to check:

Walmart – Stocking Samsung's licensed cards.

Target – Also offering preorders on the official 256GB card.

Amazon – Has a wide selection but sells out quickly.

GameStop – May carry licensed cards later in the year.

It’s a good idea to shop early if you want one, especially if you’re planning to preorder your Nintendo Switch 2. These cards are expected to be very popular, and it may take some time before stock becomes widely available.

Final Thoughts

The Nintendo Switch 2 is bringing big upgrades in power, graphics, and speed—and to keep up, you’ll need a fast storage solution. A microSD Express card is the best way to expand your storage without sacrificing performance.

Whether you go for an official licensed card or a third-party one, just make sure it has the EX logo and is made by a trusted brand. Prices may be a bit high, especially for large sizes, but the extra space and speed will be worth it—especially for those who love downloading games and playing on the go.

So as you prepare to grab your new console, don’t forget the memory card. It’s a small accessory, but it’ll make a big difference in your Nintendo Switch 2 experience.
