Here's your chance to get in on the best Prime Day Micro SD card deal for your Steam Deck or Nintendo Switch. As part of its counter Prime Day sale, Walmart is offering a 512B SanDisk Ultra Micro SDXC card for only $19.99. Walmart+ members get automatic free shipping, otherwise you'll need to get your order total over $35 to get free shipping (just buy two). SanDisk, which is owned by WD, is the most popular brand of flash memory devices. In fact, all of the official Nintendo Switch memory cards are actually rebadged SanDisk Micro SD cards.
512GB SanDisk Ultra Micro SD Card for $19.99
The Nintendo Switch and Switch OLED have 32GB and 64GB of internal storage, respectively, some of it reserved for the OS. To give you an idea of how paltry those capacities are, Zelda: Tears of the Kingdom uses up 16GB and Breath of the Wild about 13.5GB. If bought digitally, those two games alone would take up all of your internal storage on the OG Switch console. If there's any one Switch accessory that we think is absolutely required, it's a high-capacity memory card.
The Steam Deck is equally space constrained. Although it starts out with more base storage (64GB to 512GB), Steam games can easily take up far more space than that base storage. For example, the best games to play on Steam Deck take up over 60GB each. Even if you opted for the 512GB model, you're going to run out of space sooner than you think. For more information, check out our Steam Deck review or, for that matter, our Asus ROG Ally review.
The SanDisk Ultra Micro SD card offers an extra 512GB of storage on top of your base capacity. It's compatible with virtually any device that accepts the Micro SDXC card standard including the Nintendo Switch, Steam Deck, and the ROG Ally. This is a U1 A1 V10 rated card with up to 120MBps read speeds. There are faster cards out there, but the Nintendo Switch can't take advantage of such speeds. An SD card adapter is also included in the packaging.
This is easily one of the best Steam Deck deals and Nintendo Switch deals available for October Prime Day, and absolutely worth considering if you find yourself short on space all too often.
