2.9.3 Altitude
2.9.4 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.
2.9.4.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of
70 Gs (read) and 40 Gs (write) based on half-sine shock pulses of 2 ms during read operations. Shocks should not be repeated
more than two times per second.
2.9.4.2 Non-operating shock
3TB, 2TB and 1TB 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.
2.9.5 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.
2.9.5.1 Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards specified in this
document are specified below.
* Rotary Random Operating 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. Throughput may vary if improperly mounted.
2.9.5.2 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.
Operating –304.80 m to 3048 m (–1000 ft. to 10,000+ ft.)
