I tested the EgoDisk on a Blackmagic URSA Mini 4.6K with various codes. From HD 1080p 24-120fps to Raw Loseless 24-60fps. I've found the only issues it has is with full lossless raw capture. 24-30 fps is fine, but higher frames are dropped. So a high frame rate above 30 will not work on this card. You need a card that writes faster. I would like to thank EgoDisk for an available map to capture in my raw settings. I guess give them more time and I'm sure they'll come out with a card that writes at an incredible speed. However, I haven't tested it with Alexa Mini yet. This is next.
