What Kind of SD Card for Switch 2?

The Switch 2 uses a new storage standard called microSD Express. It is the only card type that lets you store and play games on the console.

Standard microSD cards still work in the Switch 2, but only for screenshots, videos, and file transfers. You cannot save or play games on them. This is a Nintendo design choice, made to keep game performance consistent across all users.

So when you shop, do not just grab any microSD card. Look for the right standard.

What is microSD Express?

microSD Express is a faster type of memory card based on the SD 7.1 specification. It uses a PCIe 3.0 interface, the same kind of connection used by modern SSDs. That gives it a theoretical top speed of about 985 MB/s.

For comparison, that is roughly 9.5 times faster than the standard UHS-I cards used by the original Switch. The result is faster game loading and quicker file transfers.

The Switch 2 is currently the only device that uses microSD Express. The standard has been around since 2019, but it has been slow to spread. That limited adoption explains the higher price of these cards today.

How to Spot a microSD Express Card

Two visual cues make it easy.

• Look for the "EX" logo. Every true microSD Express card prints "EX" on the label. Do not confuse it with "Extreme," which is a marketing name used by some standard cards.

• Check the pins. Flip the card over. microSD Express cards have two rows of metal pins, while standard cards have only one. The second row is what carries the higher speed signals.

Why Do You Need An SD Card?

The Switch 2 has 256GB of UFS 3.1 internal storage. That sounds like a lot. But the system uses about 7GB, so you start with around 249GB of usable space.

Modern games eat that fast. Here are a few examples in 2026:

Just four AAA games can fill half your console. If you share the Switch 2 with family, the limit comes even faster. A microSD Express card is the only way to add more game storage.

This is also useful if you upgraded from a Switch 1. Your old microSD card will not run your games on the Switch 2, but you can still pull screenshots off it. For the full upgrade flow, see how to transfer data from Switch to Switch 2.

Available Sizes: 128GB to 1TB

In 2026, microSD Express cards come in four main sizes. The Switch 2 can support up to 2TB, but 1TB is the biggest you can buy right now.

If your library is small, a 256GB card is plenty. If you plan to keep many AAA titles, jump to 512GB or 1TB.

Understanding Speed Classes

microSD Express cards have their own speed classes. They are marked with an "E" followed by a number. The number is the minimum sustained write speed in MB/s.

In real Switch 2 gaming, even the slowest microSD Express cards perform within a few percent of the fastest ones. The Switch 2's internal storage is still quicker, so game loading from a card depends more on the console than the card. For most players, any reputable microSD Express card will feel great.
