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.
