It is a chip that senses sudden movement or sudden stops. For example, someone pushes the computer from a table with a sharp shove. The computer drops to the floor with a sudden stop. The SMS is supposed to detect this and lock the hard drive and optical drive to prevent damage to the drive heads and to any inserted media. Of course, it can't work with an SSD which does not have moving parts.
