If you're building a digital game library, you're likely aware of the limited internal storage on the Nintendo Switch. The Switch and Switch OLED come with 32GB and 64GB respectively, with some space reserved for the operating system. Many games take up significant storage—Tears of the Kingdom requires 16GB, Monster Hunter Rise uses 20GB, Breath of the Wild needs 13.5GB, and Persona 5 Royal occupies 14GB. Since the Switch has only one memory card slot, it's wise to invest in the largest card you can, though 1TB should be more than enough for most users.

The SanDisk ImageMate Pro works with virtually any device that supports the Micro SDXC standard, including the Nintendo Switch, Steam Deck, and ASUS ROG Ally. It outperforms standard Micro SDXC cards with its U3 / A2 / V30 speed ratings, delivering sustained read speeds of up to 200MBps and write speeds of 140MBps. This card is ideal for gadgets that demand fast, high-capacity storage, such as smartphones, 4K DSLR cameras, or action cameras.
