Summary
TheNintendo Switch 2will support microSD Express cards, according to several newly surfaced SKUs believed to belong to some of its accessories. This leak hence suggests thatNintendo’s upcoming console will offer massive storage technology improvements compared to its predecessor.
The Switch2 is widely rumored to have entered mass productionin the final stretch of 2024, possibly as early as late September. This belief is reinforced by a massive influx of leaks detailing the console’s hardware that have been surfacing online since Q4 2024.
In a continuation of this trend, several GameStop stock keeping units (SKUs) said to belong tounannounced Switch 2 accessoriesleaked in early January 2025. The product labels, originally shared by Reddit user Opposite-Chemistry96, mention a trio of “Switch 2 Exp Micro SD Card” products, with capacities ranging from 256GB to 512GB. These designations appear to refer to cards based on the microSD Express standard, a storage interface that’s significantly more advanced than the one supported by the Switch.
Nintendo Switch 2 May Offer 900% Faster microSD Transfer Speeds
TheNintendo Switch supports UHS-I microSD cards, which offer theoretical maximum transfer speeds of around 104 MB per second. In practice, even the best-in-class products based on this interface typically cap out at approximately 95 MB/s. Meanwhile, the microSD Express standard can feasibly achieve transfer speeds in the ballpark of 985 MB/s. This 900% improvement stems from the technology’s reliance on the non-volatile memory express (NVMe) protocol for highly parallel data transfer, the same one used by the fastest modern SSDs.

Another big advantage that microSD Express cards have compared to their UHS-I counterparts concerns their maximum capacity. While the older standard caps at 2TB, the newer one supports cards that are up to 128TB in size—a 6,300% improvement. According to the image of GameStop’s internal inventory management system shared by Opposite-Chemistry96, the retailer plans to sell the 256GB Switch 2 cards for $49.99. Meanwhile, the sole 512GB card listed in GameStop’s system has an $84.99 price tag attached to it.
Opposite-Chemistry96 also uncovered SKUs for a Switch 2 carrying case and two “deluxe” cases, priced at $19.99 and $29.99, respectively. All of these offerings are likelyunofficial Switch 2 accessories, the kind of product that has been leaking online for months now. Nintendo has so far twice said it will officially reveal its next console before the end of its current fiscal year. The company has two and a half more months to make good on that promise, as its ongoing fiscal period concludes on Jun 28, 2025.
