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).

Note.

To maintain optimal performance drives should be run at nominal drive temperatures 
and humidity.

See 

Section 2.11, "Reliability"

 for rated MTBF device operating condition requirements.

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

Section 3.4

). 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, 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

2.6.2

Effective Altitude (sea level)

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.

Operating:

–304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)

Non-operating:

–304.8 m to 12,192 m (–1000 ft. to 40,000+ ft.)
