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.
See
Section 2.11, "Reliability"
a. Operating
41°F to 158°F (5°C to 70°C) temperature range with a maximum temperature gradient of 36°F (20°C) per hour as reported by the
drive.
The maximum allowable drive reported temperature is 158°F (70°C).
Air flow may be required to achieve consistent nominal drive temperature values (see
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, monitor the current drive temperature using the SMART
temperature attribute 194 or Device Statistics log 04h page 5.
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.
2.6.1
Humidity
The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).
2.6.1.1
Relative humidity
Operating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Non-operating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.

Effective Altitude (sea level)
Operating:
–304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)
Non-operating:
