your definetly not going to be able to fully utlize a gigabit line... 80 mabey 90% max... more like 75% utlization. even then ur gonna need some fast hds on the client and host side as 75% of a gigabit connection results in 93mb/s... then it comes down to hardware used as the files need to go from hd, to hd controler, to sb, out to pci or pcie buss, to nic card... then the reverse form at the other comp...
THE QUICKEST way to get files from one comp to another would be 2 computers with raid 0 hds able to sustain over 100mb/s and a crossover cat5 e cable directly linking the 2 together, plugged into gigabit ethernet ports... ull get about another 10% utlization over the standard computer to router to computer setup.
