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).
To maintain optimal performance drives should be run at nominal drive temperatures and humidity
Note
See
Section 5.0, "Reliability specifications"
6.6.1
Temperature
a. Operating
41°F to 140°F (5°C to 60°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 140°F (60°C).
Air flow may be required to achieve consistent nominal drive temperature values (see
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 Temperature log page
(0Dh), with PARAMETER CODE 0000H TEMPERATURE. The TEMPERATURE field (byte 9) indicates the temperature of the SCSI
target device in degrees Celsius at the time the LOG SENSE command is performed.
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.
6.6.2
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.
6.6.3
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)
