I'm moving a bunch of data from a 1TB external drive to a new 2TB drive. The two fastest options appear to be using the Restore function of Disk Utility or a 3rd party utility like CCC (which I have, and use for backups). Any comments on which of these (or perhaps some other option) is best? The only big difference I can see between these two is that since Disk Utility uses block transfers (essentially a "perfect" image of the original) and CCC uses rsync (a file-transfer utility) the CCC copied disk will use the space on the new drive more efficiently. I suspect Disk Utility might be faster, but I don't know that for certain.
