512 GB UHS-I card for 4K capture

The SanDisk Extreme Pro SDXC card delivers 512 GB of storage for cameras that use the UHS-I interface. It supports U3, V30 and Class 10 ratings for sustained video recording. Photographers and videographers who need reliable capacity for high-resolution files will find it suitable.

UHS-I bus caps read at 200 MB/s

The UHS-I bus limits maximum read throughput to 200 MB/s even with a compatible reader. Write performance reaches 140 MB/s, which meets the V30 guarantee of 30 MB/s minimum sustained speed. Faster transfer rates would require a UHS-II or UHS-III card and matching host device.

Verify your device accepts SDXC and UHS-I

Check that your camera, drone or recorder explicitly supports SDXC cards up to 512 GB and the UHS-I speed class. Older hosts limited to SDHC or lower speed classes will not recognise the full capacity or achieve the rated performance. A UHS-II reader is needed to reach the 200 MB/s transfer figure.

Questions about this item

Should I choose the 512GB capacity or a smaller 64GB card for 4K video?

The 512GB card holds far more 4K footage than a 64GB card, reducing the need to swap media during long shoots.

What does the 200MB/s read speed mean when I offload files to my computer?

With a compatible reader like the SanDisk Professional PRO-READER, you can transfer a full card of data at up to 200MB/s, cutting post-production wait time.

How does the UHS-I U3 V30 rating affect real-world recording?

The U3 and V30 ratings guarantee a minimum sustained write speed of 30MB/s, ensuring stutter-free 4K UHD video capture at the card's rated 140MB/s shot speed.
