It's possible that cp would attempt to create a new cdrom device
rather than copy the data; it won't with the default options, though.
dd can also be useful when you can't easily redirect stdout; e.g.

tar cf - . | ssh somewhere dd of=blah.tar

An earlier thread resulted in a claim that specifying a block size can
make things faster, but without giving any hard evidence on the
matter.  I'd be curious to see the results of such a test, but not
curious enough to actually run one myself :-)
