Will this CFexpress Type B Card Work with Nikon Z Series Cameras?

Yes, Nikon has released firmware to allow the Nikon Z6 and Z7 to work with CFexpress cards.

Is CFexpress Type B compatible with XQD?

Certain cameras that use XQD memory cards can get a firmware update from the device manufacturer to allow that device to use CFexpress Type-B cards.

Will the 128GB Capacity Work for Canon Eos R5 8K Raw Video?

ProGrade Digital's recommendation would be to purchase the 512 GB Gen 2 CFexpress memory card to support 8k video capture. We just recently received our camera, and we are in the process of putting the cards through our rigorous testing. So far our 512GB and 1TB Gen 2 cards are able to handle 8K.
