The Samsung Pro Plus works seamlessly with any Micro SDXC-compatible device, including Nintendo Switch, Steam Deck, and ASUS ROG Ally. Outperforming standard Micro SDXC cards, it carries U3/A2/V30 speed ratings—delivering sustained read speeds up to 180MB/s and write speeds up to 130MB/s. This makes it perfect for high-speed data transfers on devices like 4K DSLRs, action cameras, or gaming handhelds.

Notably, the Nintendo Switch OLED offers only 64GB of internal storage (with less usable due to OS requirements), while the original Switch has just 32GB. For context, "Tears of the Kingdom" occupies 16GB, and "Breath of the Wild" takes up 13.5GB—meaning digital copies of these two games alone could fill the base Switch entirely. With just one expansion slot available, opting for the largest affordable card is wise, though 512GB typically suffices.

Will This Card Work With Nintendo Switch 2?

No—Switch 2 will require MicroSD Express cards to leverage higher speeds, though these currently command premium prices. While conventional Micro SD cards peak at 104MB/s, MicroSD Express utilizes PCIe/NVMe tech to achieve blistering speeds up to 985MB/s.
