    Hi,

    I have just upgraded my MBP mid 2012 non retina with a 1TB SSD Crucial M550 1TB.

    I have a question regarding the Sudden Motion Sensor (SMS).

    Should this be disabled?

    If not disabled will it damage the SSD in case of a sudden motion?

    What happens if it is disabled having only the SSD installed.

    Are there any features that must be disabled apart from the SMS? for example hibernation etc...?

    Is trim really needed? Can it damage the SSD?

    Thanking you in advance.

    1. You can if you want to.
    2. No. Your SSD contains no moving parts, leaving it enabled or not has no effect at all in case of an SSD.
    3. Nothing.
    4. No. Disabling the SMS isn't a "must" either.
    5a. It helps in putting off the performance degradation SSD's go through with time.
    5b. No. It was a command invented for SSD's, the only reason for it's existence is SSD's.
