The Samsung Pro Plus works with virtually any Micro SDXC-compatible device, including Nintendo Switch, Steam Deck, and ASUS ROG Ally. With U3/A2/V30 speed ratings, it achieves sustained read speeds up to 180MB/s and write speeds up to 130MB/s - making it ideal for 4K cameras or gaming handhelds requiring fast data transfers. The bundled USB card reader enables easy file transfers to PCs, even without a data cable.
This card perfectly suits the Nintendo Switch ecosystem. The base Switch and Switch OLED offer only 32GB and 64GB internal storage respectively (partially reserved for system functions). For perspective, Tears of the Kingdom occupies 16GB while Breath of the Wild needs about 13.5GB - together they'd fill the original Switch's storage if downloaded digitally. Since the Switch has just one memory slot, maximum capacity matters, though 512GB satisfies most users' needs.
Will This Work With Nintendo Switch 2?
No - the upcoming Switch 2 requires faster Micro SD Express cards to leverage the console's enhanced capabilities. While current Micro SD cards max out at 104MB/s via UHS-I, Micro SD Express utilizes PCIe/NVMe technology to reach speeds approaching 985MB/s. These newer cards are already available but remain significantly more expensive than standard Micro SD options.
