MicroSD Express: The New High-Speed Storage Standard for Nintendo Switch 2

The article explains the MicroSD Express format, a new standard introduced in late 2023 that delivers significantly faster data transfer speeds than traditional MicroSD cards. Previously limited to high-end digital cameras, MicroSD Express is now essential for the Nintendo Switch 2, which requires it for saving game data and files. These cards boast sustained write speeds from 150MB/s to 600MB/s, using a new pin layout while maintaining backward compatibility with older readers. However, due to their novelty, these cards are expensive and not widely available. A 128GB Express card costs around $50, significantly more than the $10-$20 price range of standard equivalents. Despite the cost, the speed advantage is notable—tests show large game transfers on the Switch 2 taking less than half the time compared to older systems. While Express cards are likely overkill for general users, they are highly recommended for Switch 2 owners due to the growing size of modern games and the performance benefits they provide.
