I'd not expect cp to be significantly slower or faster than tar etc. dd 
just copys bytes, it does nothing to interpret them as a filesystem, so 
there's no way for dd to change the filesystem (but it can, for example, 
copy /dev/hda2 to ~/hda2.img where you can then mount them as 
filesystems and play with cp, tar and so on.
