    Seems some ppl experiments delays when the SMS ask the SSD to park heads (What, no heads here), then the SSD is disabled for a few seconds.
    *dont try if u r on HD

    sorry if discused before , didnt found it, w/ the search :)


    $sudo pmset -g

    if return 1, = SMS is enabled

    to Disable:
    sudo pmset -a sms 0
    sudo pmset -g, if returns 0, then success

    to Enable:
    sudo pmset -a sms 1
    sudo pmset -g, if returns 1, then success
