If you've been building a digital game library, you're likely aware of the limited internal storage on the Switch. The standard Switch and Switch OLED models come with 32GB and 64GB of onboard storage, respectively, some of which is used by the system software. Many popular titles consume a large portion of this space—for instance, The Legend of Zelda: Tears of the Kingdom uses 16GB, Monster Hunter Rise requires 20GB, Breath of the Wild takes 13.5GB, and Persona 5 Royal needs 14GB. Since the Switch has only one memory expansion slot, it's wise to invest in the largest card your budget allows, though most users won't require more than 1TB of additional storage.
The PNY Premier-X works with almost any device that supports the Micro SDXC standard, including the Nintendo Switch, Steam Deck, and Asus ROG Ally. It outperforms many standard Micro SDXC cards with its U3, A2, and V30 speed ratings. In practical terms, it offers sustained read speeds of up to 100MB/s and write speeds of up to 90MB/s. This makes it an excellent choice for devices that demand fast, high-capacity data transfers, such as smartphones, 4K DSLR cameras, or action cameras.
