1 TB UHS-II SDXC card

This SanDisk Extreme PRO SDXC card provides 1 TB of storage with a UHS-II interface. Rated read speeds reach up to 280 MB/s and write speeds up to 150 MB/s. It carries a Video Speed Class 60 rating for sustained 60 MB/s capture. The card operates from -25 °C to 85 °C and stores from -40 °C to 85 °C.

Who this suits and who should look elsewhere

The V60 and U3 ratings suit videographers recording 6K, 4K or Full HD footage and photographers shooting continuous RAW bursts. Buyers who need higher sustained write speeds for 8K workflows or who require CFexpress Type B compatibility should consider other formats.

Build fit: devices and workflow

The card fits any device with a UHS-II SDXC slot and works in UHS-I slots at reduced speed. Fast offloads up to 280 MB/s reduce ingest time when paired with a compatible reader. RescuePRO Deluxe recovery service is included for accidental file deletion. The compact 0.09" x 0.94" x 1.26" form factor leaves room for adjacent cards in multi-slot bodies.

Questions about this item

Do I need a UHS-II compatible SD card reader to reach the 280MB/s transfer speed?

Yes, a UHS-II reader is required to achieve the full 280MB/s read rate; UHS-I readers will fall back to their lower maximum speed.

Will this card work in my older camera that only supports UHS-I?

It is backward compatible with UHS-I cameras, but write speeds will be limited to the camera's UHS-I maximum instead of the card's 150MB/s capability.

How can I verify the card is sustaining the 60MB/s write speed needed for 6K video?

The V60 marking on the card guarantees a minimum sustained write of 60MB/s; camera firmware will also show the active video speed class during recording.
