www.seagate.com Drive Specifications 2.9 Environmental specifications 2.9.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions. Operating: Non-operating: 0° to 60°C (32° to 140°F) -40° to 70°C (-40° to 158°F) 2.9.2 Temperature gradient Operating: Non-operating: 20°C per hour (68°F per hour max), without condensation 30°C per hour (86°F per hour max) 2.9.3 Humidity 2.9.3.1 Relative humidity Operating: Nonoperating: 5% to 95% non-condensing (30% per hour max) 5% to 95% non-condensing (30% per hour max) 2.9.3.2 Wet bulb temperature Operating: Non-operating: 37.7°C (99.9°F max) 40°C (104°F max) 2.9.4 Altitude Operating: Non-operating: -304.8 m to 3,048 m (-1000 ft. to 10,000+ ft.) -304.8 m to 12,192 m (-1000 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 70 Gs based on half-sine shock pulses of 2 ms during read operations. Shocks should not be repeated more than two times per second. 2.9.5.2 Non-operating shock 1000 and 750GB models 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 2 ms duration.
