www.seagate.com Drive Specifications 2.9.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.9.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 80 Gs based on half-sine shock pulses of 2 ms during read operations. Shocks should not be repeated more than two times per second. 2.9.5.2 Non-operating shock 3TB, 2TB and 1.5TB models The non-operating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs based on a non-repetitive half-sine shock pulse of 2 ms duration. 1TB, 750GB, 500GB, 320GB and 250GB models 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 non-repetitive half-sine shock pulse of 2ms duration. 2.9.5.3 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below. 2Hz to 22Hz 22Hz to 350Hz 350Hz to 500Hz 0.25 Gs (Limited displacement) 0.50 Gs 0.25 Gs 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. Throughput may vary if improperly mounted. 2.9.6 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 22Hz 22Hz to 350Hz 350Hz to 500Hz 3.0 Gs (Limited displacement) 3.0 Gs 3.0 Gs Seagate Desktop HDD Product Manual, Rev.
