Solid State Disk vs. Sudden Motion Sensor

Lucky owners of a Solid State Disk (SSD) should think about disabling their Suddden Motion Sensor (SMS) which is primary used to protect mechanic hard disks from head crashes. With SSDs head crashes are history - you can work without fear, even if your hardware rumbles.

However, follow these instructions to disable the sensor:
  • open a terminal
  • disable sensor: sudo pmset -a sms 0 (0 = disable, 1 = enable)
  • check actual settings: sudo pmset -g
