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 70 Gs
based on half-sine shock pulses of 2ms during read operations. Shocks should not be repeated more than two times per second.
2.9.5.2 Non-operating shock
4-6TB 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 2ms duration.
8TB 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 250 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 0.25 Gs (Limited displacement)
22Hz to 350Hz 0.50 Gs
350Hz to 500Hz 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
