Its always better to use the named devices than absolute devices
Don’t ask me why. Something to do with device access and permissions.
And note that it’s usually a good idea to supply a blocksize with something like bs=1M (or even 10M); if you let dd use its default blocksize, you’ll be waiting around forever.
