You *can* do that, yes. The major win with dd onto a raw device is
that you can specify the block size. For most USB sticks, using a
block size of 4MB or so is going to be *much* faster than using the
default for dd (512 bytes) or cp (10 KB IIRC). cat using the shell
redirection is often going to be using a small size (1 page?).

  Debian does NOT ship free CDs. Please do NOT contact the mailing
  lists asking us to send them to you.
