gigabit switches are CHEAP, you can pick one up that supports jumbo frames for under 50 bux, and yea if you are recording live TV and moving it to storage it sucks up lots of time and I have lots of home users that are doing this.
Its not just for GB files either, those pesky 700 MB files fly. just last night i moved 400 pictures around my network to show a friends wife on the big screen, that was 1.86 GB, poof.... fast.
USB 3.0? what so we can go back to sneeker netting with USB flash drives.. awesome... ugh.... no thanks, there is a reason networking was created.
Go enjoy your high tech floppy disks............ blah!
