The Samsung Pro Plus 512GB Micro SDXC card is compatible with a wide range of devices, including the Nintendo Switch, Steam Deck, and ASUS ROG Ally. Designed for performance, it features speed ratings of U3 / A2 / V30, delivering up to 180MB/s sustained read speeds and 130MB/s sustained write speeds. This makes it ideal for gaming handhelds, 4K cameras, and other devices that demand fast data transfer and large storage capacity. The included USB card reader allows for easy file transfers to your PC without needing an additional cable.
For Nintendo Switch owners, this card serves as a perfect solution to the console’s limited internal storage—32GB for the original model and 64GB for the OLED version, some of which is reserved for system use. For example, games like *The Legend of Zelda: Tears of the Kingdom* take up around 16GB and *Breath of the Wild* about 13.5GB. Together, they would consume nearly all available space on the original Switch if downloaded digitally. With only one expansion slot available, investing in a high-capacity card like the 512GB Samsung Pro Plus ensures you’ll have plenty of room for your growing game library, although most users won’t need more than that.
Is This Memory Card Compatible with the Nintendo Switch 2?
Unfortunately, the Samsung Pro Plus Micro SDXC card will not be compatible with the upcoming Nintendo Switch 2, which is expected to support the newer Micro SD Express standard. These next-gen cards leverage PCIe and NVMe technology to reach blazing-fast speeds of up to 985MB/s—far beyond the 104MB/s limit of traditional Micro SD cards using UHS-I. While Micro SD Express cards are already available, they’re significantly more expensive and offered by only a few select brands.
