Ethernet throughput will be slower than with FW 400...
Really? Both Macs have gigabit ethernet, so theoretically the Ethernet throughput (1,000 megabits/sec, or 125 megabytes/sec) would be more than twice that of FW 400 (400 megabits/sec, or 50 megabytes/sec). Real-world variables would lower both of those rates, but I'm guessing Ethernet would more than hold its own.
The googleshpere is non-definitve.
