Fast and reliable

The 325 GB cards worked perfectly in my Nikon Z9, reading and writing without any delays or problems. Yes, the card warms up a lot in heavy use, both in camera and the PG05.5 reader, but this did not affect performance.

Best CF Express Card I’ve used.

What is CFexpress?

CFexpress is a removable media standard created by the CompactFlash Association. There were three form factors defined in the standard; Type A, Type B, and Type C. All form factors leverage the PCIe® Gen 3 interface for higher performance based on a computing industry storage interface and utilize NVM Express™ 1.3 protocols. For more information visit compactflash.org

Will this 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 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.

Do you make a CFexpress reader?

We make two different CFexpress readers; our Dual-Slot CFexpress and SD Reader and the 

Thunderbolt™ 3 CFexpress and XQD reader.

Do you guys make a XQD reader?

We make a CFexpress reader that is backward compatible with XQD once you download the XQD driver from Sony.

Will the Cobalt Series handle 8K Raw video?

Yes, both the 325GB and 650GB will handle 8K video with no issues.

Will this card work with the Red V-Raptor?
