A new Nintendo Switch 2 system update is delivering a frustrating surprise for some players: certain MicroSD Express cards are suddenly no longer being recognized for game storage. That’s a major problem for anyone who’s been using these fast, higher-end cards to expand the Switch 2’s limited internal space and build a larger digital library.
The issue started appearing shortly after the Switch 2 firmware update version 22.0.0 rolled out on March 16. While many fans have been enjoying the update’s headline addition—boost mode for select last-generation titles—multiple reports say the update may also be triggering storage compatibility errors. After installing the firmware, affected consoles can display messages indicating the inserted MicroSD Express card is incompatible, preventing installed games from launching and forcing players to rely only on the Switch 2’s 256GB internal storage.
Most complaints center on the 1TB MicroSD Express card from PNY, which has become a popular choice among Switch 2 owners looking for a large-capacity expansion option. One user reports that after the update, the console stopped accepting the card as MicroSD Express storage for games. Interestingly, the card may still partially function, but only as a standard MicroSD card—meaning it can be used for limited tasks like transferring screenshots and video, rather than storing and running Switch 2 games. Because the Switch 2 requires the MicroSD Express standard for game storage, that “fallback” behavior isn’t much comfort for players who suddenly can’t access their installed titles.
Some users tried basic troubleshooting such as cleaning the card and checking for debris. When reaching out for help, at least one player says Nintendo support didn’t provide an immediate fix, leading them to contact PNY for assistance. PNY reportedly had not seen the same issue widely with the 1TB model and asked for the card to be sent in through an RMA process for testing.
Although PNY dominates the conversation, the problem may not be limited to a single manufacturer. Other posts suggest that additional MicroSD Express models could be affected, including a 1TB option from Integral under the Gamer’s Edge X line. For Switch 2 owners, that raises a worrying question: is this a brand-specific failure, or a broader compatibility bug introduced by the firmware update?
What makes this situation especially painful is how essential MicroSD Express has become for the Switch 2 experience. Modern game installs can be enormous, and some titles can take up close to (or more than) 90GB. If you’re using game-key style releases that still require substantial downloads, your storage can fill up quickly—especially with only 256GB onboard. When that happens, expandable storage isn’t just a convenience; it’s practically required for players who want multiple big games installed at once.
One commonly suggested workaround is reformatting the card using a Windows PC. However, that approach comes with a major downside: it erases everything on the card, including your installed games. The silver lining is that save data is stored on the console’s internal storage, so players generally won’t lose game progress—but they may have to redownload large titles, which can be time-consuming and hard on slower internet connections.
There’s also the money factor. High-capacity 1TB MicroSD Express cards can cost $200 or more, even with long warranties. With memory pricing under pressure due to supply constraints, many buyers aren’t expecting these cards to get significantly cheaper anytime soon. That makes the idea of a firmware-related malfunction even more aggravating for anyone who invested in premium expandable storage.
For now, Switch 2 owners who rely on MicroSD Express for game installs will be watching closely for answers. Whether this requires a Nintendo firmware fix, a card firmware/tool update from manufacturers, or a combination of both, players are hoping for a fast resolution—because without reliable MicroSD Express support, the Switch 2’s storage situation becomes a lot tighter overnight.
