If you're building a digital game library, you're likely aware of the limited storage on the Nintendo Switch. The Switch and Switch OLED come with 32GB and 64GB of internal storage respectively, with a portion reserved for the operating system. Large games like Tears of the Kingdom (16GB), Monster Hunter Rise (20GB), Breath of the Wild (13.5GB), and Persona 5 Royal (14GB) can quickly eat up that space. With only one memory card slot available on the Switch, opting for a high-capacity card like the SanDisk ImageMate Pro is essential. While most users won't need more than 1TB of additional storage, this 512GB card offers a great balance of size and price.

The SanDisk ImageMate Pro is versatile, compatible with any device that supports the Micro SDXC card standard, including the Nintendo Switch, Steam Deck, and ASUS ROG Ally. It outperforms many other Micro SDXC cards with its impressive speed rating of U3 / A2 / V30, offering up to 200MBps read speeds and 140MBps write speeds. This makes it an excellent choice for devices requiring fast and high-capacity storage, such as smartphones, 4K DSLRs, or action cameras.

Important Note: Incompatibility with Nintendo Switch 2

This card will not work with the upcoming Nintendo Switch 2, which will require the newer Micro SD Express format. If you're planning ahead for the Switch 2, you can find compatible cards already available on Amazon.
