Environmental Specifications

This section provides the temperature, humidity, shock, and vibration specifications for Laptop Thin drives.
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
Above 1000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet.

2.8.1

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.
2.8.1.1 Operating shock
These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 400 Gs
based on half-sine shock pulses of 2ms. Shocks should not be repeated more than one time per axis
2.8.1.2 Nonoperating shock
The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when
subsequently put into operation is 800 Gs based on a nonrepetitive half-sine shock pulse of 2 ms duration.
The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when
subsequently put into operation is 1000 Gs based on a nonrepetitive half-sine shock pulse of 1 ms duration.
