Seagate Enterprise Capacity 3.5 HDD v5 SAS Product Manual, Rev. F 33
6.5.1 Temperature
a. Operating
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature range with a maximum
temperature gradient of 36°F (20°C) per hour.
The maximum allowable drive case temperature is 140°F (60°C).
Air flow may be required to achieve consistent nominal case temperature values (see Section 10.2). 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, measure the case temperature of the drive. See Figure
7 for HDA case
temperature measurement location.
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.
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)
