Environmental specifications

2.9.1

Drive case temperature

This section provides the temperature, humidity, shock, and vibration specifications. Ambient temperature is
defined as the temperature of the environment immediately surrounding the drive. Above 1000ft. (305 meters), the
maximum temperature is derated linearly by 1°C every 1000 ft. Drive case temperature should be measured at the
location indicated in

Temperature gradient

Operating 20°C per hour (68°F per hour max), without condensation
Nonoperating 30°C per hour (86°F per hour max)

Altitude

Operating –60.96m to 3048m (–200 ft. to 10,000+ ft.)
Nonoperating –60.96m to 12,192m (–200 ft. to 40,000+ ft.)
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 2ms during read operations. Shocks should not be
repeated more than two times per second.
2.9.5.2 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 300 Gs (for 3TB and 2TB model) and 350 Gs (for 1TB)
based on a nonrepetitive half-sine shock pulse of 2ms duration.
