SanDisk microSD Express Card for Nintendo Switch 2: review
If you’re looking for one of the best Nintendo Switch 2 microSD Express cards, then you can’t go wrong with the SanDisk microSD Express Card for Nintendo Switch 2.
This recent release from storage giant SanDisk is officially licensed by Nintendo, so you don’t need to worry about any potential compatibility issues. It also boasts an attractive Mario red design that helps it stand out compared to the numerous non-gaming options on the market.
It even comes in cheaper than some unlicensed alternatives like the PNY microSD Express Card – at least for the time being – so you’re not getting ripped off for wanting a Nintendo-approved model. The card performed well in benchmarks, achieving an average read speed of 894.4 MB/s and write speed of 674.1 MB/s and even beating the manufacturer’s own claimed figures (though this is likely just the result of different testing conditions).
It was actually the fastest read speed among the models that I tested for comparison, which included the aforementioned PNY alternative and the officially licensed Samsung microSD Express Card for Nintendo Switch 2.

It also impresses in the real world. As you would expect, given those strong benchmark results, I never experienced any noticeable loading time slowdowns while playing fast-paced games like Mario Kart World and Donkey Kong Bananza.
File transfer speeds on the console itself were good, too. My 60.5GB installation of Cyberpunk 2077: Ultimate Edition was copied to the micro SD Express card in a total of 14 minutes and 25 seconds, then moved back to the internal storage in 12 minutes and 1 second. A smaller game, the brand new Pokémon Legends: Z-A, moved to the card from the internal storage in 1 minute 48 seconds, then back in 1 minute 16 seconds.
This is one of the best Nintendo Switch 2 accessories, and the only downside is your limited options when it comes to the card’s capacity. There’s just one 256GB model, which should be enough for most users, but not if you have a particularly large game collection. Hopefully, there will be some more variants on the way, but in the meantime, the great value Lexar Play Pro microSD Express Card has you covered with its mega 1TB capacity.

How I tested the SanDisk microSD Express Card for Nintendo Switch 2
- Tested against other microSD Express Cards
- Using a range of benchmarks
- Real-world use also evaluated
I reviewed the SanDisk microSD Express Card for Nintendo Switch 2 alongside three other Nintendo Switch 2-compatible microSD Express models, including the Lexar Play Pro microSD Express Card and PNY microSD Express Card, for the purposes of side-by-side comparison.
I tested the sequential read and write speed of each card using a standardised benchmark via CrystalDiskMark in its default flash memory settings. In order to facilitate this, I relied on the Lexar Play Pro MicroSD Express Card Reader, which features active cooling via a fan.
To see the real-world performance, I used each card with my personal Nintendo Switch 2 – playing a range of games and timing different file transfers on the system itself.
