How we chose and tested

We evaluated microSD cards based on read and write speeds, capacity options, reliability ratings, and real-world value for the Nintendo Switch hardware. Since the Switch uses a UHS-I bus with a practical speed ceiling around 95 to 100 MB/s, we focused on cards that consistently hit that limit rather than those with specs the console can't use. We prioritized UHS-I cards with U3, V30, and A2 ratings, and considered brand reputation, warranty coverage, and user feedback across multiple sources to build a balanced list.

The best microSD cards for Switch right now

SanDisk 512GB Extreme - Best overall

The SanDisk 512GB Extreme hits the sweet spot of speed, capacity, and durability. With read speeds up to 190 MB/s and an A2 rating, it handles game downloads and open-world loading better than most alternatives, even if the Switch caps the usable speed. It's a reliable pick for anyone who wants a card that just works across a big library.

Samsung EVO Select 512GB - Best value

Read speeds of 130 MB/s exceed Nintendo's recommended range, and the A2 rating keeps the system feeling fast.

Silicon Power 256GB Superior - great for indie games on a budget.
SanDisk 256GB Extreme Pro - top performance, but you’ll pay for it.

How to Choose

Capacity. This is the biggest decision. If you buy physical cartridges, 128GB to 256GB is plenty. If you go all-digital, aim for 512GB or 1TB. Most Switch games range from 5GB to 20GB, so a 256GB card holds roughly 15 to 20 major titles.
Speed class. The Switch uses a UHS-I bus that caps out around 100 MB/s. You don't need expensive UHS-II or UHS-III cards. Look for UHS-I, U3, V30, and preferably A2 rated cards for the best experience.
A2 vs A1 rating. A2 cards handle random read and write operations much better than A1 cards. This matters for game loading and menu responsiveness. If the price difference is small, go with A2.
Brand trust. Stick with well-known names like SanDisk, Samsung, Kingston, and Lexar. Counterfeit cards are common, and a deal that looks too good to be true almost always is. Buy from reputable retailers.
Licensed vs unlicensed. Officially licensed Nintendo cards offer guaranteed compatibility and fun designs, but they cost more. Unlicensed cards from major brands work just as well for less money.

FAQ

Does the Nintendo Switch need a microSD card?

Not right away, but you'll run out of space quickly if you download games. The standard Switch has only 32GB of internal storage, and big titles like The Legend of Zelda: Tears of the Kingdom take up around 16GB on their own. A microSD card is the only way to expand storage.

What size microSD card should I get for Switch?

For most people, 256GB or 512GB is the sweet spot. A 256GB card holds roughly 15 to 20 major games. If you mostly play indie titles or buy physical cartridges, 128GB may be enough. All-digital gamers should consider 512GB or 1TB.

Will my Switch microSD card work on the Switch 2?

No. The Nintendo Switch 2 requires microSD Express cards, a new and faster format. Standard microSD cards from the original Switch will not play games on the Switch 2, though they can still be used to transfer screenshots and videos.

Do I need a fast card or just a big one?

Capacity matters more than speed for the Switch. The console caps read speeds around 100 MB/s, so any UHS-I card that meets that threshold will perform similarly during gameplay. Focus on getting enough storage first, then look for A2 rated cards for better random performance.

Are officially licensed Nintendo cards worth the extra cost?

They offer guaranteed compatibility and fun designs, but you're paying a premium for the logo. Unlicensed cards from SanDisk, Samsung, or Kingston with the same specs work identically for less money. The licensed cards make good gifts for kids or Nintendo fans who appreciate the themed artwork.
