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
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 10
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)
NOTE
To maintain optimal performance drives should be run at nominal drive temperatures and humidity
