The Nintendo Switch 2 experienced stock shortages during its initial two months but is now more readily available. If you are a current or prospective owner, you may want to consider purchasing a microSD card, as the console’s internal storage capacity of 256GB may not be sufficient for all your games. It is essential to note that only microSD Express cards are compatible with the Switch 2 for game storage. In contrast, cards used with the original Switch or Switch Lite will only serve limited functions, primarily allowing access to previously captured screenshots or video clips.
The microSD Express cards offer a significant performance upgrade, advertising a 4.4 times improvement in transfer speeds compared to older microSD versions. This enhanced speed is marked by a small “EX” emblem on the card.
Availability of both the Switch 2 and microSD Express cards has improved, but it’s important to mention that these cards can be expensive, with some priced above $50 for just 256GB of storage. While the Switch 2 can support microSD Express cards up to 2TB, 1TB remains the largest size readily available, often retailing for up to $200. The Walmart Onn model offers a more affordable 512GB option at approximately $65.88, although stock may vary.
