Environmental specifications
This section provides the temperature, humidity, shock, and vibration specifications for Barracuda drives. 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. Refer to
Section 3.4 on page 20
for base plate measurement location.
