The Samsung Pro Plus works with any device supporting the Micro SDXC standard, such as the Nintendo Switch, Steam Deck, and ASUS ROG Ally. It's a high-speed card with U3 / A2 / V30 ratings, delivering sustained read speeds up to 180MBps and write speeds up to 130MBps. It’s perfect for 4K DSLRs, action cameras, or gaming handhelds that demand fast, high-capacity storage. The included USB reader simplifies file transfers to your PC, even without a data cable.
This card is also compatible with the Nintendo Switch. The Switch and Switch OLED come with limited internal storage—32GB and 64GB, respectively—part of which is taken by the OS. For example, The Legend of Zelda: Tears of the Kingdom uses 16GB, while Breath of the Wild uses about 13.5GB. If you purchase both digitally on the original Switch, they’d almost fill the internal storage. The Switch has one memory card slot, so it’s wise to choose the largest card within your budget, though 512GB is ample for most users.
Is this memory card compatible with the Nintendo Switch 2?
No, this card won’t be compatible with the upcoming Switch 2, which requires Micro SD Express cards to leverage the console’s faster speeds. If you're prepping for the Switch 2, MicroSD Express cards are available now, though options are limited and prices are higher than standard Micro SD cards. While traditional Micro SD cards max out at 104 MB/s via UHS-I, MicroSD Express cards use PCIe and NVMe technology to achieve speeds up to 985 MB/s.
