Shock may be applied in the X, Y or Z axis. 2.9.5.1 Operating shock The drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs (Read) and 30 Gs (Write) based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second. 2.9.5.2 Non-operating shock The non-operating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration. 2.9.6 Vibration All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis. 2.9.6.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below 5Hz to 22Hz 22Hz to 350Hz 350Hz to 500Hz 0.25 Gs 0.50 Gs 0.25 Gs 2.9.6.2 Non-operating vibration The maximum non-operating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below. 5Hz to 350Hz 350Hz to 500Hz 3.0 Gs 3.0 Gs 16 Pipeline HD.2 Series SATA Product Manual, Rev.
