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).
Note.
To maintain optimal performance drives should be run at nominal drive temperatures and humidity.
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).
Note.
Operating drive temperature references temperature reported by the drive on Log Page 0Dh
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).
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 ft (–304.8 to +3048 m)
b. Non-operating
–1000 to +40,000 ft (–304.8 to +12,192 m)
