Professional 512GB CFexpress Type B card

The SanDisk Extreme PRO 512GB CFexpress Type B card delivers read speeds up to 1700 MB/s and write speeds up to 1400 MB/s. It is built for professional photographers and videographers who need reliable capture of raw 4K video and high-resolution images. The 512GB capacity supports extended shooting sessions without frequent card changes.

CFexpress Type B interface constraints

The card uses the CFexpress Type B form factor, which requires a compatible camera slot or reader. Backward compatibility exists only with select XQD cameras that have received specific firmware updates enabling CFexpress support. Older XQD bodies without that firmware cannot use this card, and standard SD or CFexpress Type A slots are physically and electrically incompatible.

1400 MB/s sustained write speed

This maximum write speed is the specification that determines whether the card can keep pace with your camera's raw 4K recording bitrate. If your workflow demands sustained throughput at or near this level for long takes, verify your camera's required write speed before purchase. Buyers needing higher sustained write rates for 8K or high-frame-rate raw formats should look elsewhere.
