256 GB SDXC UHS‑II card

The SanDisk Extreme PRO SDXC card delivers 256 GB of storage with UHS‑II transfer rates. It is built for professional photographers and videographers who need reliable capture of high‑resolution stills and cinema‑quality video.

Who this suits and who should look elsewhere

This card suits creators recording 6K, 4K UHD or Full HD video at sustained write speeds of 60 MB/s and shooting continuous RAW bursts at up to 150 MB/s. Buyers who only shoot occasional JPEGs or standard‑definition footage will not need the V60 rating or the 280 MB/s offload speed.

Deciding spec: V60 sustained write speed

The Video Speed Class 60 rating guarantees a minimum sustained write speed of 60 MB/s, which is the single specification that determines whether the card can handle real‑time 6K and 4K UHD recording in your camera.

Questions about this item

How much heat or power draw does the 280 MB/s read speed create during all-day shoots?

The card draws power only from the host slot and runs at UHS-II voltages; no active cooling is required for continuous 6K capture at the rated 60 MB/s sustained write speed.

What host slot and file system does the 256 GB card need to reach its 150 MB/s write speed?

A UHS-II SDXC slot is required; the card arrives formatted exFAT so it works immediately in cameras and readers that support SDXC.

Will the card keep up with an older UHS-I body when I shoot 4K UHD at 3840×2160?

In a UHS-I slot the card falls back to UHS-I bus speeds, so sustained write drops below the 60 MB/s V60 guarantee and 4K recording may not be reliable.
