sorry...that was a typo. (corrected to SSD) ...I meant DJI's cineSSD cards. Point is still the same. They do write 6k to that card, and as Eric said, it's a really nice file. Canon, Sony, Arri all require you to invest in some truly magical 24k gold Truffled hard drives and recorders and readers to do the same thing.
Canon's presentation (so far) shows RAW output via SDI. If 3rd party recorders like Odyssey7Q+ or Atomos Sumo or Inferno wants to support it, they can. However, so far Convergent Design and Atomos haven't seen a market worth supporting. CFast is not fast enough for RAW, at least not the way Canon puts the card into an enclosure (Arri Mini leaves it hanging on the outside allowing more cooling for pushing the CFast faster.)
AFAIK Codex drives are the same as on Arri SXT, LF, 65 and can be used on XT too, Varicam 35 & Pure. So easier for rental house to keep inventory, which cuts costs significantly. But obviously not tailored towards wide market owner/ops.
