M.2 vs regular SSD

hi can someone please give me a run down of the M.2 vs regular SSD battle for Alienware laptop?

for now, all I can see is just portability and slightly less weight than regular SSD drive? does M.2 has better power consumption also?

TIA for any answer, this will help me buy my AW13
