The Nintendo Switch 2 uses MicroSD Express cards — a different standard from the regular microSD in the original Switch. Your old card won’t work for game storage. Quick answer: the Lexar Play Pro is the one I’d buy. If price is the priority, the SanDisk microSD Express is a solid alternative.
When shopping, look for the “EX” logo on the card or packaging — that’s how you confirm it’s a genuine MicroSD Express card.
Recommended MicroSD Express Cards for Nintendo Switch 2
Lexar Play Pro MicroSD Express (256GB–1TB)
Rated at 900 MB/s read and 600 MB/s write — the fastest specs in the current MicroSD Express lineup. Available in 256GB through 1TB. The 512GB hits the right balance of capacity and price for most Switch 2 owners; the 1TB is worth it if the Switch 2 is your primary console and you buy a lot of third-party titles. Amazon / B&H
SanDisk microSD Express (128GB, 512GB)
Rated at 880 MB/s read and 650 MB/s write. A reliable alternative to the Lexar — similar speeds, widely available, and often priced competitively. The 512GB is the most practical size for most users. Amazon / B&H
Samsung MicroSD Express — Nintendo Licensed (256GB)
Rated at 800 MB/s read. Nintendo’s officially licensed option from Samsung. The rated speed is lower than the Lexar or SanDisk, and it’s only available in 256GB, which limits its appeal for larger libraries. Best suited for younger kids with modest game collections who want a guaranteed-compatible card. Amazon
PNY MicroSD Express (128GB, 256GB)
Rated at 890 MB/s read and 750 MB/s write — strong write specs on paper. Available in 128GB and 256GB only, which limits it for anyone building a larger library. A reasonable option if you find it on sale or if 256GB covers your needs. Amazon / B&H
All MicroSD Express Cards Available
Here is the full list of MicroSD Express cards currently on the market. Shop around — prices shift often. Some of the lesser-known brands in this list are white-label cards made by the same NAND suppliers as the major names and relabeled.
Does the Switch 2 Work with Standard microSD Cards?
No. The Nintendo Switch 2 does not support standard microSD cards (UHS-I or UHS-II) for game storage. The Switch 2’s storage interface runs on PCIe/NVMe — the same technology used in SSDs — which is fundamentally different from the older UHS bus. Standard cards physically fit the slot, but the console won’t use them for games.
Standard microSD cards can store screenshots and video captures, but that is the extent of their compatibility. For anything game-related, you need MicroSD Express.
What Capacity Do You Actually Need?
The Switch 2 ships with 256GB of internal storage. For a younger kid playing primarily first-party Nintendo titles — Mario Kart, Splatoon, Zelda — you might not need an Express card right away. Nintendo’s own games are well-optimized and small by modern standards. Where storage fills up fast is third-party and live-service games: Fortnite, Call of Duty, and modern AAA ports can run 60–100GB each.
As a father of two, I’ve seen how quickly “just one more game” empties a console’s internal storage. Here is how I’d think about capacity:
256GB: Right for younger kids playing mostly Nintendo titles. Comfortably fits 15–20 first-party games.
512GB: The practical choice for most Switch 2 owners. Covers a mixed library — Nintendo games plus larger third-party titles — without constant storage management. This is the size I’d start with.
1TB: Worth it if the Switch 2 is your primary console and you buy third-party games regularly. Cheaper to start here than to buy a smaller card and replace it six months later.
Avoid Fake and Used Cards
Don’t buy used memory cards, and be skeptical of no-name brands at steep discounts. During my 2025 testing for the Retroid Pocket 5, I had a microSD card physically melt — it burned a hole through the adapter and would have destroyed the console’s card reader if I hadn’t caught it. High-speed Express cards generate real heat under sustained writes; cheap or worn-out cards aren’t built to handle the power draw. Stick to Lexar, SanDisk, Samsung, and PNY from authorized retailers.
