128 GB SDXC card for 4K capture

The SanDisk Extreme Pro SDXC card delivers 128 GB of storage for cameras and recorders that use the UHS-I interface. It carries U3, V30 and Class 10 ratings so sustained write performance meets the demands of 4K UHD video workflows.

Built for tough environments and fast offload

The card is engineered to withstand water, shock and extreme temperatures, making it reliable for outdoor and travel shooting. QuickFlow technology optimises transfer speeds up to 200 MB/s when paired with the SanDisk Professional PRO-READER, while shot speeds reach 140 MB/s for continuous bursts.

Check device compatibility before ordering

Verify that your camera or recorder supports SDXC cards and the UHS-I bus to use the full speed potential. Devices limited to SDHC or older speed classes will not achieve the rated write or transfer figures. Buyers needing capacities beyond 128 GB should look at higher-capacity models.
