Drive Specifications
2.6
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).
2.6.1
Temperature
a. Operating
41°F to 158°F (5°C to 70°C) drive case temperature range with a maximum temperature gradient of 36°F (20°C) per
hour.
The maximum allowable drive case temperature is 158°F (70°C).
Air flow may be required to achieve consistent nominal case temperature values (see Section 2.6). 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 2
for HDA temperature checkpoint.
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.

2.6.2
Humidity
The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).

Effective Altitude (sea level)
Note
To maintain optimal performance drives should be run at nominal drive temperatures and humidity.
Note
Seagate does not recommend operating at sustained case temperatures above 60°C
Operating at higher temperatures will reduce useful life of the product.

Operating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Nonoperating:
5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Operating:
–304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)
Nonoperating:
–304.8 m to 12,192 m (–1000 ft. to 40,000+ ft.)
