Review on 📷 PERGEAR CFE Type-B Memory Card | 1600MB/s Stable Stream Speed | Photos, 4K 120P 8K RAW Video | Compatible with Canon EOS R5, Nikon Z6 Z7, Panasonic S1, S1R, S1H (512GB) by John Bourgeois

Tried this card on my Z7 and found it to work very well. There's not a huge difference in buffer clearing time for CF Express or XQD cards on the Z7, but it's nice to have a card that's more forward-thinking than XQD format cards. The capacity is also great for shooting 4K video or without having to switch cards for a full day of shooting. Fast transfers add to the benefits of the card!
