The record-breaking Nintendo Switch 2 continues to power through the summer, and while the console is now available at Amazon, some fans have been finding it tricky to find a compatible microSD card that’s in stock, or even just at a reasonable price.
Thankfully, Walmart has come through with the goods this week. While we’ve seen 256GB that can double your Switch 2’s storage, this 512GB option is in stock at $78, which is the best price we’ve found for a card of this size that you can buy right now.

YMMV: Stock is region dependant.
This 512GB microSD Express Card is Ideal for Nintendo Switch 2
We add that caveat, because Walmart does have an onn microSDXC Express Card which is slightly cheaper. It’s been out of stock for some time, too, making this SanDisk offering your best bet.
Amazon still has the microSD Express from Samsung with Mario branding, but it’ll set you back $59. For just under $20 more, you’re getting double the storage.
It also features the same 512GB SanDisk card, but is listed for $120 instead of $78 and has delayed delivery through to August or September. So that’s a huge $42 off when buying via Walmart, and faster shipping to-boot.
If you were planning to use your existing Nintendo Switch 1 card for your Switch 2, then there’s bad news: Switch 2 requires microSD Express cards, which have higher speeds but also (sadly) come at a higher price.
Thankfully, the new cards are easy to pop in, and you won’t see any performance drops versus using the internal system storage (the Switch 2 has 256GB, at least, a sizeable increase on the first Switch’s 32GB).
In other Switch 2 news, the official Switch 2 Pro Controller is finally available to buy at Amazon. It’s a new listing that’s popped up following a quiet resolution between Amazon and Nintendo, who had been in a months-long standoff. The thaw has also brought a fresh Amazon listing for Donkey Kong Bananza, which launches later this week on July 17.
