Environmental Specifications

This section provides the temperature, humidity, shock, and vibration specifications for Seagate Laptop SSHD 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.

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 350 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.
