There are only few options, 1. Use USB controller Chip that support 10Gbit or more. 2. Use 10Bit or more ethernet, Optical or copper. 3. Use PCIe 4. Use onboard storage. 5. Use HDMI or something custom and have another receiver (They are called frame grabber and everybody hate them).

Right now there are not many controllers on market that can do more than 5Gbit

Most useable solution is to use Ethernet , I would say optical.

Typically what cameras like the Edgertronic do are have 8-16 GB of onboard DDR3-4 RAM and write raw frames directly to memory on a trigger or a loop/trap. Then when you have X amount of frames you want, process them using ffmpeg/gstreamer using onboard hardware acceleration methods and write to an SD card / network drive / attached SSD or similar. Simply bind X GB of RAM to a memdisk and write to that path in Linux, for example.

I am fine doing this and have done it using raspiraw and know the Edgertronic platform / source code very well. The problem is that sensors and MIPI lanes on commercially-available products are complete trash with even worse documentation.
