Drive Specifications
2.8.4 Altitude
2.8.5 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.
2.8.5.1
Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum operating
shock of 80 Gs (read) / 70 Gs (write) based on half-sine shock pulses of 2ms during read operations. Shocks should not be
repeated more than two times per second.
2.8.5.2
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 300 Gs based on a non-repetitive half-sine shock pulse of
2ms duration.
2.8.6 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. Throughput may vary if improperly mounted.
2.8.6.1
Operating vibration
The maximum vibration levels that the drive may experience while meeting the performance standards specified in this
document are specified below.
2.8.6.2
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.
