My current office design studio is being moved to a home based set-up consisting of 2x mac pro workstations + 1x mac pro server (6tb storage). The two macs will need network access to each other and the server. Files being copied across this network will be large (1-3gb) so needs to be fairly fast. How do I go about implementing a high-speed ethernet network? I am at present using Powerline (Home plug) adaptors via ethernet to run broadband to the office rather than wi-fi. This works well for internet access, but my guessing is Powerline will be too slow to use as a network for mac file transfer?
