If the notion of doing this is to reduce fragmentation and enhance performance, then the 'erase, drag and drop' methodology would be better as that will write each file, one at a time, as a contiguous entity. IIRC, SuperDuper makes volume clones, which preserve the exact block structure of the clone source volume, preserving whatever fragmentation might exist. .
Another excellent utility, ChronoSync by Econ Technologies, is what I use for this sort of thing rather than the Finder, however. ChronoSync works as a synchronizer primarily but is also very good at volume to volume file duplication because you can turn on enhanced verification, have it create a log of its operation, and if you need to interrupt it in the middle of the task, when you restart it will pick up where it left off and save a lot of time. However, for video editing you should have your scratch disk completely independent of the video editing source AND destination disks. All connected with eSATA or FireWire800 ... That promotes better performance and minimizes fragmentation. yes, video editing eats disk space ...
