6.5
Environmental limits
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part.
Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).
6.5.1
Temperature
a. Operating
41°F to 131°F (5°C to 55°C) drive temperature range with a maximum temperature gradient of 36°F (20°C) per hour.
The maximum allowable drive temperature is 140°F (60°C).
b. Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that
the drive is packaged in the shipping container designed by Seagate for use with drive.
6.5.2
Humidity
The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).
a. Operating
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
b. Non-operating
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
6.5.3
Effective altitude (sea level)
a. Operating
–1000 to +10,000 feet (–304.8 to +3048 meters)
b. Non-operating
–1000 to +40,000 feet (–304.8 to +12,192 meters)
Note
To maintain optimal performance drives should be run at nominal drive temperatures and humidity.
Note
Operating drive temperature references temperature reported by the drive on Log Page 0Dh
Note
Air flow may be required to achieve consistent nominal drive temperature values (see Section 9.2). To
confirm that the required cooling is provided for the electronics and HDA, place the drive in its final
mechanical configuration, and perform random write/read operations. After the temperatures stabilize,
read drive temperature from Temperature Log Page (0Dh).
