NAS for serving 4-5 4K BluRay movies simultaneously

[Enquiries]

I want to be able to serve 4-5 different 4K movies simultaneously. I have been trying to calculate processor speed/power and connectivity speed to achieve this goal. An I9 processor may be able to process the data but without 4 lanes of 10g connectivity it may not be able to send the data to all 4 viewers. Any help with my weak math skills would be appreciated!
