Blackmagicdesign URSA - Getting Started with Your URSA; Selecting the Right CFast Card

Choosing a CFast 2.0 Card
When working with high data rate video it’s important to carefully check the CFast card you
would like to use. This is because CFast 2.0 cards have different read/write speeds. Some
cards can record sustained RAW video, and some are suited to compressed recording using
ProRes and compressed RAW formats.
The following CFast 2.0 cards are recommended for 4K ProRes 422 HQ (up to 60 fps)
