Where to Buy microSD Express Cards for Nintendo Switch 2: A 2025 Buyer’s Guide

Wondering where to buy microSD Express cards for your Nintendo Switch 2? If you’re searching for the best microSD cards compatible with the latest Switch model, it’s crucial to choose the right type—only microSD Express cards truly unlock the full potential of your new console. Unlike the original Switch or Switch Lite, the Switch 2 requires these faster cards to efficiently store and play games, thanks to its advanced specs and increased data transfer speeds.

MicroSD Express cards are marked with a small but important “EX” logo on the card and packaging. This subtle emblem indicates that the card supports PCIe NVMe SSD speeds, delivering up to 4.4 times faster transfer rates than standard microSD cards. Using a regular microSD card with your Switch 2 means you’ll only be able to access old screenshots or video clips—not play games or store new data. So, spotting the “EX” label is essential to avoid compatibility issues.

When it comes to purchasing microSD Express cards, price and availability vary widely. These cards tend to carry a premium price tag due to their advanced technology. For example, 256GB models can exceed $50, while larger capacities like 1TB can reach up to $200. Though the Switch 2 supports cards up to 2TB, 1TB is currently the largest commonly available capacity—and often out of stock. Walmart’s Onn brand offers a more affordable alternative, with its 512GB microSD Express card priced around $65.88 when available, making it a popular choice for budget-conscious gamers.

Fortunately, the Switch 2 comes with 256GB of built-in storage, so immediate upgrades aren’t necessary for everyone. But if you’re a serious gamer or plan to download many titles, investing in a microSD Express card is wise to ensure smooth gameplay and quick load times.

Before purchasing, always verify that the card’s packaging clearly shows the “EX” label to avoid incompatible products. Buying from trusted retailers also helps guarantee authenticity and better warranty coverage.

By choosing the right microSD Express card, you’ll maximize your Nintendo Switch 2’s performance, improve your gaming experience, and future-proof your storage needs.
