I prefer CCC, but I'm biased, since I moderate the Bombich forums <http://forums.bombich.com/>. Cloning with a 27"iMac i7, 12 GB RAM, FW 800, it's copying 1.5 GB/minute. Your initial clone should take about 11 hours. Incrementals afterwards depend on how much was changed. BTW, don't push the limits of your target volume. Consider getting a larger disk.
