April 2, 2025, San Jose, CA, USA—The first 1TB micro SD Express card in history is being shipped by Lexar, a well-known worldwide brand of flash memory solutions. For handheld video games, the PLAY PRO micro SDXC Express Card offers much better performance thanks to its construction on the new SD card standard, which merges PCI Express 3.0 and NVMe 1.3 interfaces.

Unmatched Speed and Capacity

The PLAY PRO micro SDXC Express Card has the best rates in the micro SD Rapid card standard, with up to 900MB read and 600MB/s write1. This gives gamers an incredible performance boost that speeds up downloading and game loads. With a 1 TB3 capacity, it can accommodate a lot of huge AAA games. Although it is prepared for the future for tomorrow's state-of-the-art small video games and other emerging devices that will make use of this next-generation technology, it is reversibly compatible with UHS-I and UHS-II host devices.

Nintendo Switch 2 Compatibility With Caveats

A significant disclaimer was included with the news, though: the console is only supported with micro SD Express. According to Nintendo's support site, the cards that most people use today, which are based on the outdated UHS-I bus interface, are only capable of loading screenshots and videos from an original Switch; they cannot be used to play games.

Switch 2’s Storage Strategy

Notably, the Switch 2 technically comes with far more extensive 256GB of storage by default. Nintendo claims that this restriction is required to maintain the Switch 2's performance enhancements. However, if you ever want to increase the device's storage, this modification will probably make it more expensive to do so and significantly reduce your alternatives.
