Professional 4K workflow card

The SanDisk Extreme Pro SDXC card targets photographers and videographers who need reliable UHS-I performance for 4K UHD recording. Its 128GB capacity suits extended shoots without frequent media swaps. The U3 and V30 ratings guarantee the sustained write speeds required for professional capture workflows.

128GB capacity with 90MB/s write ceiling

Sequential write speeds reach 90MB/s, providing enough headroom for continuous 4K UHD video and high-resolution burst photography. The 170MB/s read speed accelerates offloading large media libraries to editing workstations. Capacity runs out on multi-day 4K projects or uncompressed RAW+JPEG bursts that exceed the 128GB limit before backup.

Weather-resistant build for field reliability

The card is engineered to withstand water, shock, temperature extremes and X-ray exposure encountered in outdoor production. This ruggedisation protects irreplaceable footage when shooting in rain, dust or rough transit. No bundled recovery software or adapters are included, so users must supply their own card readers and backup strategies.

Questions about this item

Will this 128GB SDXC card work in my older camera that only takes SDHC cards?

No. SDXC cards require an SDXC-compatible host; older SDHC-only devices cannot address the 128GB capacity.

How can I verify the card delivers the rated 170MB/s read and 90MB/s write speeds after I install it?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sequential results should approach 170MB/s read and 90MB/s write.

Does the package include a card reader or adapter, or do I need to buy one separately?

The box contains only the 128GB Extreme Pro SDXC card; a UHS-I card reader or USB adapter must be purchased separately.
