The record-breaking Nintendo Switch 2 is still dominating the summer gaming scene, and while the console is now available at Amazon, many fans have hit a snag: finding a compatible microSD card that’s both in stock and affordably priced.
Good news—Walmart has stepped in with a solid solution. While a 256GB card can double your Switch 2’s base storage, this 512GB SanDisk GamePLAY microSD Express Card is currently in stock for just $78, marking the best available price we’ve seen for this capacity.

Why This 512GB microSD Express Card Is Ideal for Nintendo Switch 2
While Walmart does offer a slightly cheaper onn microSDXC Express Card, it’s been consistently out of stock—making this SanDisk option your most reliable choice right now.
Amazon still carries the microSD Express card from Samsung with Mario branding for $59, but it only offers 256GB. For less than $20 more, the SanDisk 512GB card doubles your storage capacity.
Another Amazon listing for the same 512GB SanDisk card asks $120—with delivery delayed until August or September. That makes Walmart’s $78 price a $42 savings, plus you get faster shipping.
Important: Your Old microSD Card Won’t Work
If you were hoping to reuse your original Nintendo Switch microSD card with the Switch 2, here’s the catch: the Switch 2 requires microSD Express cards. These support faster data speeds essential for the new console’s performance—but come at a higher cost than standard microSD cards.
The good news? These new Express cards are simple to install, and you won’t experience any performance loss compared to the internal storage. The Switch 2 comes with 256GB of internal storage—a major leap from the original Switch’s 32GB.

Alongside the controller, Amazon has also launched a fresh listing for Donkey Kong Bananza, set to release on July 17.
