The 256GB microSD Express Memory Card from SanDisk features a storage capacity of 256GB and takes advantage of its NVMe PCIe 3.1 interface to support the capture of 5.3K and 4K video at 30 fps, slow-mo Full HD video at 60 fps, and 10MP raw image bursts without dropping shots. It can achieve read speeds of up to 880 MB/s and write speeds of up to 650 MB/s, with sustained write speeds that will not drop below 210 MB/s.

To help facilitate card usage in almost any environment as well as keeping your content safe, this card is resistant to water, temperature, humidity, drops, shocks, magnets, x-rays, and wear. Furthermore, SanDisk ThermAdapt helps keep this card from overheating. Should this card's data become compromised, two years of RescuePRO Deluxe is included for free.

Please note that while this card is backward compatible with UHS-II and UHS-I devices, it will operate at UHS-I / U3 speeds, even when used in UHS-II devices. Also supported is the A1 spec for use in mobile devices.

Ready for Tomorrow

A PCIe 3.1 NVMe interface and a standard microSD UHS-I interface make this card compatible with today's devices and primed for future superspeed products.

Exponentially Faster Performance

This microSD Express card delivers up to 8.8x faster read speeds than SanDisk's standard UHS-I microSD card and up to 4.4x faster read speeds than their fastest UHS-I microSD card that have adopted a version of SanDisk QuickFlow technology.

With a capacity of 256GB, users will experience read speeds of up to 880 MB/s, write speeds of up to 650 MB/s, and sustained write speeds of 210 MB/s when used with SanDisk's PRO-READER Express Dual Card (sold separately).

A Massive Time-Saver

A microSD Express card reduces your wait time significantly. When paired with the SanDisk PRO-READER SD Express Dual Card (sold separately), it saves you up to 2.8 minutes transferring 60 minutes of 4K UHD video shot at 30 fps and up to 2.9 minutes transferring 2000 10MP raw photos. You'll also be able to transfer a 2-hour HD movie that has been downloaded from a streaming site to the microSD Express card in less than 3.5 seconds.

Durability You Can Count On

Adventure without worry knowing the microSD Express cards, like SanDisk's standard microSD cards, are waterproof, temperature-proof, humidity-proof, drop-proof, shock-proof, magnetic-proof, x-ray proof, and wear-out proof. And SanDisk ThermAdapt helps keep devices from overheating with a specially designed enclosure and controller that uses dynamic adaptive thermal management.

Trust SanDisk with Your Content

SanDisk knows microSD Express inside and out. They helped initiate the standard and continue to drive its development to this day, just as we led development of the UHS-II, UHS-I, and non-UHS microSD card formats. They use proprietary Flash Management Techniques to produce highly stable memory.

Full File Recovery

Nothing satisfies quite like capturing the right shot or scene, and nothing frustrates more than accidentally deleting it. With the included RescuePRO Deluxe file recovery software offer, you can recover files free of charge for two full years.

Exceptional Capture

Although made for future products, SanDisk microSD Express cards deliver exceptional performance right now. They capture brilliant 5.3K and 4K video seamlessly at 30 fps, and slow-motion Full HD at 60 fps. They also record 10MB raw images in continuous burst mode without dropping shots.
