The SanDisk GamePlay microSD Express is a 512GB card built on the PCIe Gen 3-NVMe microSD Express standard, rated up to 880MB/s read and 650MB/s write with 210MB/s sustained write. It is aimed at Nintendo Switch 2 owners and handheld gamers who want faster load times, and it also handles 5.3K video and 10MP RAW capture in compatible cameras. It is backward compatible with UHS-I and UHS-II devices, though those slots run at their own slower speeds. Against ordinary UHS-I microSD cards it is far quicker in Express-capable hardware, but it costs more and only pays off if your device supports the standard.

The SanDisk GamePLAY microSD Express card has 512GB of storage and is made for handheld gaming. It works with Nintendo Switch 2. It also works with current microSD UHS-I and UHS-II devices.
It uses a PCIe Gen 3 NVMe interface, which brings performance comparable to a basic portable SSD. Read speeds reach up to 880MB/s, write speeds up to 650MB/s, and sustained write speeds 210MB/s. With the SanDisk PRO-READER SD Express Dual Card reader (sold separately), a 2-hour HD movie download transfers in less than 3.5 seconds.
The card supports up to 5.3K video and 10MP RAW image capture. Its burst and sustained recording speeds are faster than those of a SD UHS-II card. SanDisk ThermAdapt technology uses a specially designed enclosure and an adaptive thermal controller to help keep devices from overheating.
