CFexpress cards for RedEdge-P and Altum-PT

What CFexpress cards are recommended for use with my RedEdge-P or Altum-PT?

The Delkin Devices Power CFexpress card (model DCFX1-128) has been tested to work for RedEdge-P and Altum-PT. Other CFexpress cards may not be readable by the camera or provide optimal performance. If you choose to purchase additional CFexpress cards, we recommend you get the exact same model as the one provided with the camera. Example below:



Can I use a higher capacity than the included 128GB?

Yes, provided that it is formatted to FAT32 rather than exFAT.

High capacity storage devices tend to use the exFAT format, but our camera firmware prefers the FAT32 file system for optimal performance. Formatting the card using the camera web UI will automatically change the file system to FAT32. For more information, refer to the next question.


How do I format my CFexpress card to FAT32?

The best way to format your storage device to FAT32 is using the camera's web UI. See: How to format a storage device using the web UI.

It will format to FAT32 by default. You can also format using your computer.

  • If using macOS Disk Utility, erase the volume by choosing the "MS-DOS (FAT)" option. This also applies to Ubuntu OS.
  • If using Windows, it will not allow you to format to FAT32 by default. You will need to download a third-party tool to accomplish this. 

How do I test my Storage Device?

If you suspect the storage device's transfer speeds is affecting your data (such as inconsistent capture intervals), consider testing the storage device by following our guide: How to Test a Storage Device Using a MicaSense Sensor?



If the web UI does not recognize your CFexpress card, be sure that it is the Delkin Power DCFX1-128 model. This is the approved and validated model.
