Read and Write Speeds


ProGrade Digital introduced the first 1TB CFexpress card back in 2018. Now two years later, Delkin has doubled the capacity with a slight edge in maximum performance of 1730 MB/s when comparing the ProGrade Digital CFexpress models that top out at 1700 MB/s. The Delkin cards utilize 3rd generation PCI Express interface and support NVM Express for its fast recording speeds that are compatible with 8K, 6K, and 4K at high frame rates and bitrates. The cards also support RAW continuous-burst shooting without delay.

Compatibility Chart


Delkin also promises each card has "undergone extensive testing" to be compatible with several brands including Canon, Nikon, and Panasonic. The cards are said to work with the Canon C500Mark II, 1DX Mark III, Nikon's Z6 and Z7, and Panasonic's LUMIX DC-S1 and S1R cameras. This excludes the LUMIX DC-S1H, but Delkin is currently testing the C300 Mark III and the yet to be released Canon EOS R5.

While the CFexpress cards are not backward compatible with either CompactFlash or CFast 2.0 hosts, Delkin does offer a 48-hour replacement guarantee for all non-working cards, and each card is serialized for added protection. Exact pricing hasn't been released, but the 1TB model sells for $699. Keep an eye out for the 2TB version coming soon.
