The Samsung Pro Plus is compatible with virtually any device that supports the Micro SDXC card standard, including the Nintendo Switch, Steam Deck, and ASUS ROG Ally. Boasting a speed rating of U3 / A2 / V30, it delivers up to 180MBps read speeds and 130MBps write speeds, making it ideal for devices requiring fast, high-capacity transfers, such as 4K DSLRs, action cameras, or gaming handhelds. The included USB card reader simplifies file transfers to your PC without the need for additional cables.

This card is also perfect for the Nintendo Switch and Switch OLED, which come with limited internal storage of 32GB and 64GB respectively, part of which is reserved for the operating system. For context, games like "Tears of the Kingdom" and "Breath of the Wild" take up 16GB and 13.5GB respectively. With only one memory card slot available on the Switch, opting for a large capacity card like the 512GB Samsung Pro Plus is a smart move, ensuring you have ample space for your digital game library.

Is this memory card compatible with the Nintendo Switch 2?

Unfortunately, this card will not work with the upcoming Nintendo Switch 2, which requires the newer Micro SD Express cards to leverage its higher speed capabilities. If you're specifically looking for a Switch 2 memory card, MicroSD Express cards are available, albeit pricier and with fewer brand options compared to standard Micro SD cards. Traditional Micro SD cards top out at 104 MB/s via the UHS-I interface, while MicroSD Express cards can reach speeds up to 985 MB/s using PCIe and NVMe technology.
