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 and 2TB 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 and 500GB 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 2-ms

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.

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.
