SanDisk Extreme PRO 256GB microSD Express Card

Move high-resolution footage, still images, and game data at PCIe-class speeds with a 256 GB microSD Express card using an NVMe PCIe 3.1 interface. SanDisk SDSQXFN-256G-GN4NN reaches up to 880 MB/s read performance and up to 650 MB/s write performance, with sustained writes rated at 210 MB/s for longer recording and transfer tasks. Its compact microSD format supports deployments where removable flash capacity must fit cameras, handheld devices, and compatible gaming hardware. Capture 5.3K or 4K video at 30 fps, slow-motion Full HD video at 60 fps, and 10 MP raw image bursts. Class 10 and U3 speed ratings address video recording requirements, while the A1 application-performance rating supports mobile-device storage use. The PCIe interface distinguishes this card from conventional UHS-only media when installed in a microSD Express host capable of accessing its higher-speed NVMe path. Backward compatibility with UHS-II and UHS-I devices helps retain use across existing equipment, although operation in those hosts is limited to UHS-I and U3 speeds. Environmental protection covers water, temperature, humidity, drops, shocks, magnets, X-rays, and wear. ThermAdapt thermal management helps control card temperature during demanding activity, and two years of RescuePRO Deluxe recovery software are included for eligible data-recovery use.
