Professional UHS-II Performance

The Extreme PRO uses the UHS-II interface to provide substantially higher transfer performance than conventional UHS-I SD cards when paired with compatible equipment. A second row of contacts on the rear of the card enables the increased bandwidth required for high-speed professional capture and transfer workflows.

To achieve the highest advertised performance, the host camera, card reader or other device must support the required UHS-II transfer speeds.

Up to 310MB/s Read Speed

Sequential read speeds of up to 310MB/s help accelerate file transfers from the memory card to a compatible workstation or storage system. This can significantly reduce offload time when working with large RAW photo collections and high-resolution video files.

Actual transfer speed varies according to the host device, card reader, workload and operating conditions.

Up to 304MB/s Write Speed

The 256GB SDSDXDE-256G-GN4IN model provides sequential write performance of up to 304MB/s. This helps compatible cameras clear their internal buffer quickly during continuous high-speed shooting and supports demanding professional recording workloads.

The 304MB/s write specification applies specifically to the current 128GB and 256GB variants of this product family.

V90 Minimum Sustained Write Performance

The V90 Video Speed Class guarantees a minimum sustained write speed of 90MB/s when used with compatible V90-enabled host devices.

This sustained performance is particularly important for professional video recording, where consistent write speed is required to prevent dropped frames or interrupted recording during high-bitrate capture.

Designed for 8K and 4K UHD Video

SanDisk designed the Extreme PRO UHS-II V90 range for demanding video applications including compatible 8K and 4K UHD recording.

Support for specific resolutions, frame rates and codecs depends on the camera, recording format, file attributes and other host-device requirements.

Ideal for High-Speed Photography

The card's fast write performance makes it well suited to sports, wildlife, event and action photography where cameras may capture long continuous bursts of high-resolution RAW or RAW+JPEG images.

Faster card writing can help the camera clear its image buffer more quickly, allowing photographers to continue shooting with fewer interruptions.

256GB Storage Capacity

The 256GB capacity provides substantial space for high-resolution photographs and large video files while reducing the frequency with which cards need to be changed or offloaded during longer shoots.

SanDisk defines 1GB as 1,000,000,000 bytes. Actual usable storage capacity is lower after formatting and system requirements.

IP68 Water and Dust Resistance

The current Extreme PRO UHS-II V90 card is tested to an IP68 rating under controlled laboratory conditions for resistance to water and dust.

The card should be clean and completely dry before being inserted into compatible equipment following exposure to water or contaminants.

Drop Resistant up to 6 Metres

SanDisk also tests this card to withstand drops from heights of up to 6 metres under its defined test conditions, helping protect stored content when working in demanding professional environments.

RescuePRO Deluxe Data Recovery

The card includes eligibility for two years of RescuePRO Deluxe data recovery software. The downloadable software can help recover certain photos, videos, documents and other files that have been accidentally deleted, corrupted or lost through formatting.

Registration and applicable terms and conditions are required.

Built-In Write Protection

A physical write-protect switch on the side of the SD card can be used with compatible devices to help prevent files from being accidentally overwritten or deleted.

Compatible with DSLR and Mirrorless Cameras

SanDisk lists the Extreme PRO UHS-II V90 card for use with compatible professional and prosumer DSLR and mirrorless cameras. Full UHS-II and V90 performance depends on support from the host device.

Lifetime Limited Warranty

The card is backed by SanDisk's lifetime limited manufacturer warranty. SanDisk specifies a 30-year warranty in Germany, Canada and other regions that do not recognise lifetime warranties.
