Some ProGrade Cobalt CFexpress memory cards may not work with Nikon Z cameras


I was told that Nikon has discovered an issue where using some ProGrade Cobalt CFexpress memory cards (available at Adorama and B&H) could display a card error and the card will be unusable. Has anyone experienced something similar? I am guessing that Nikon will be releasing a firmware update to fix this issue.

Update #1: see the list of compatible CFExpressa memory cards according to Nikon.

Update #2: here is a report from a reader:

ProGrade recently introduced the Cobalt 325GB 1600/1400 MB/s CFExpress cards, and the ProGrade Digital USB 3.2 Gen 2 Dual Slot CFExpress and SDXC Card Reader (PG-05.5) This is to confirm that the ProGrade Cobalt 325GB CFExpress card is compatible with Nikon Z7 and latest firmware 3.0. Tested on the Gigabyte X570 platform with USB 3.2 Gen 2 support. Performance is on par with the USB 3.2 Gen 2 bandwidth giving around 850/900 Write/Read MB/s transfer speeds. The SDXC reader slot provides around 250/290 MB/s Write Read speeds for SDXC memory cards (64GB Lexar 2000X, 300MB/s tested tested)
