The Nintendo Switch 2 has 256 GB of built-in storage, and with big games regularly taking 20–60 GB, it fills up faster than you’d think. The catch: the Switch 2 only accepts microSD Express cards for games. Ordinary microSD cards — including the ones from your original Switch — can’t store or run Switch 2 games; they only work for screenshots and videos.
The good news is that microSD Express cards have become cheaper and easier to find through 2026. Tom’s Hardware has benchmarked 13 cards in a Switch 2, and its main finding is reassuring: the differences in real games are tiny. So the right card is mostly about capacity, price and warranty. Below are the cards we’d consider in Europe, with euro prices where we could confirm them.

1. Samsung P9 Express — best value
Samsung’s P9 Express is the easiest card to recommend to most people. Tom’s Hardware names the 256 GB version its best budget 256 GB card, measuring around 112 MB/s when copying from the card in a Switch 2. It’s widely available in Europe, and the 512 GB model has been on sale for around €80 on Amazon.de — about €20 less than many rivals.
Its three-year warranty is shorter than the lifetime cover some competitors offer, and its write speed is slightly lower than the fastest cards, but you won’t notice that while playing.

Adata’s Premier Extreme is Tom’s Hardware’s top pick at both 256 GB and 512 GB. The 512 GB card recorded the fastest write speed of its size (about 96 MB/s), which shortens game installs slightly. It has a lifetime warranty, but it’s harder to find in European shops and can be pricey, so compare offers.

How to choose a microSD Express card
Look for the “EX” logo
Only microSD Express cards work for Switch 2 games. Look for the “EX” logo on the card or packaging, and don’t confuse it with “Extreme”, which is a product name on many ordinary cards.
Pick a capacity
256 GB doubles the console’s storage and is the cheapest entry point. 512 GB suits players who buy most games digitally. 1 TB is for big digital libraries. Avoid 128 GB cards: Tom’s Hardware found them poor value, and Deku Deals advises against them too.
Speed differences are small
All of the cards above read at roughly 108–114 MB/s in Tom’s Hardware’s tests. In Diablo IV, load times on the fastest cards were only about 1% slower than internal storage, and about 3% on the slowest. Don’t pay a big premium for a few extra megabytes per second.
Warranty and fakes
Lifetime warranties (SanDisk, Lexar, Adata, PNY) are a nice bonus. Buy from reputable retailers — Amazon itself rather than unknown marketplace sellers — to avoid counterfeit cards with fake capacities.
Buying in Europe
Memory prices rose through 2026, so microSD Express deals come and go quickly. EU purchases carry a two-year legal guarantee as a minimum. For more Switch 2 advice, see our PS5 vs Switch 2 comparison and consoles and handhelds guide.
How we choose
We haven’t benchmarked these cards ourselves. Our picks are based on Tom’s Hardware’s Switch 2 benchmarks (updated October 2026) and Deku Deals’ testing, combined with European prices from PC Games Hardware and Notebookcheck. Read more about how we research.
FAQ
Can I use my old Switch microSD card in the Switch 2?
Only for screenshots and videos. Switch 2 games must be stored on internal storage or a microSD Express card.

Not quite, but the difference in real games is very small — around 1–3% in load times in Tom’s Hardware’s tests.
What’s the biggest card the Switch 2 supports?
The Switch 2 supports cards up to 2 TB, but 1 TB is the largest microSD Express card currently on sale.
Which capacity is best value?
Usually 256 GB or 512 GB. Prices per gigabyte change with deals, so compare when you buy.
