If you're building a digital game library, you're likely aware of the limited storage on the Nintendo Switch. The standard 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 fill up that space. With only one memory card slot available, choosing a high-capacity card like the SanDisk ImageMate Pro is a smart move. While most users won't need more than 1TB of additional storage, this 512GB option strikes a great balance between size and cost.

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

Compatibility Note

Please note that this card will not work with the upcoming Nintendo Switch 2, which will require the newer Micro SD Express card format. If you're planning to upgrade to the Switch 2, you can find compatible cards available on Amazon.
