512 GB CFexpress Type-B card for professional

This 512 GB CFexpress Type-B card uses the NVMe 1.3 protocol over a PCIe Gen 3x2 interface to deliver maximum read and write speeds of 1700 MB/s. It is designed for photographers and videographers who need fast, reliable storage for high-resolution stills and video. The card is shock, UV light and X-ray proof for added durability.

Sustained write performance for long recordings

Exascend specifies a sustained write speed of 400 MB/s across all capacities, which is the figure that matters for continuous recording rather than short bursts. This steady throughput helps prevent dropped frames during extended video capture. The card is backwards compatible with some XQD cameras, though a camera firmware update may be required.

Check your camera slot and firmware before ordering

This card fits CFexpress Type-B slots only and will not work in CF or CFast slots. Verify that your camera model is listed as compatible, such as the Canon EOS-1D X Mark III, EOS R5, Nikon D6, Z6, Z7 or Panasonic Lumix DC-S1R and DC-S1. If you use an XQD body, confirm that a firmware update enables CFexpress Type-B support.

Questions about this item

Does the 1700 MB/s card generate extra heat or noise when recording continuously all day?

The card has no moving parts and produces no audible noise; sustained write speeds of 1700 MB/s are within its rated performance so heat stays within normal operating limits.

What camera firmware or slot type must I already have for this CFexpress Type B card to work?

Your camera needs a CFexpress Type B slot (not CF or CFast) and, for XQD bodies, a firmware update that enables CFexpress support.

Will the card fall back to slower speeds if I use it in an older XQD camera after the firmware update?

Yes, backwards-compatible XQD cameras will recognise the card but transfer rates will be limited to the XQD interface rather than the full 1700 MB/s.
