Almost all OEM rotors are one piece, but you can get two piece ones. For example:

These save 3.9lbs per rotor over OEM single piece rotors (13.25lbs vs ~9.35lbs) . One advantage is that you can replace the frictional area and reuse the hat. I could see this being an advantage for something really expensive like, say, carbon ceramic.
