The worlds leader in portable memory storage, Samsung, will be releasing a new microSD card on November 4, 2025. This one is the Samsung P9 Express, and while it can be used with most any microSD slot, it is made to be 100% compatible with the Nintendo Switch 2: https://www.amazon.com/Samsung-Express-microSDXC-Nintendo-AM/dp/B0FT995SPF

The Samsung microSD Express Card is designed to expand the storage capacity of the Nintendo Switch 2 and other compatible devices. Featuring the latest microSD Express interface, it delivers high-speed performance, enabling faster game loading, installations, and ample room for downloaded games, screenshots, and video clips.

And not only that, but it also features a Dynamic Thermal Guard overheating guard since all gaming devices can run or be ran hot. So that’s an interesting memory card feature.
