You do not have the capability for an M.2 SSD. You can however install a 2.5" SSD which is roughly 5x the speed of an HDD and more reliable. As far as the 3600MHz (3.6 GHz) that is the turbo speed of your CPU and is attained by the CPU itself under heavy workloads. And don't be sorry for the questions. We have all been there at one time or another.
