The SanDisk 256GB microSD Express is a PCIe Gen 3-NVMe memory card built for devices with a microSD Express slot, such as the Nintendo Switch 2. It reads far faster than UHS-I microSD cards and supports up to 5.3K video and 10MP RAW capture. It also works in standard microSD UHS-I and UHS-II slots, but at those slower speeds. Buy it for a device that can use Express; otherwise a cheaper UHS-I card does the same job.

The SanDisk microSD Express card is a 256 GB microSD card that uses a PCIe Gen 3 NVMe interface. It is built for fast file transfers, faster burst and sustained recording than an SD UHS-II card, and quicker game loading. Its performance is comparable to SanDisk's basic portable SSD.
With the SanDisk PRO-READER SD Express Dual Card reader (sold separately), a 2-hour HD movie transfers in less than 3.5 seconds. That is up to 4.4 times faster than SanDisk's fastest microSD UHS-I cards. The card supports up to 5.3K video and 10MP RAW image capture.
The card works with devices that have a microSDXC slot, including Android smartphones and tablets, action cams, drones, handheld gaming devices and laptops. It also works in microSD Express, UHS-I and UHS-II slots. In UHS-I and UHS-II devices, it performs at microSD UHS-I speeds. SanDisk ThermAdapt technology uses a specially designed enclosure and an adaptive thermal controller to help keep devices from overheating.
