NVIRONMENTAL 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). Maximum wet bulb
temperature is 82°F (28°C).

6.4.1

Temperature

a. Operating

The maximum allowable continuous or sustained HDA case temperature for the rated Annualized Failure Rate (AFR) is
122°F (50°C). The maximum allowable HDA case temperature is 60°C. Occasional excursions of HDA case
temperatures above 122°F (50°C) or below 41°F (5°C) may occur without impact to the specified AFR. Continual or
sustained operation at HDA case temperatures outside these limits may degrade AFR.
Provided the HDA case temperatures limits are met, the drive meets all specifications over a 41°F to 131°F (5°C to 55°C)
drive ambient temperature range with a maximum temperature gradient of 68°F (20°C) per hour. Air flow may be needed
in the drive enclosure to keep within this range (see Section 8.3). Operation at HDA case temperatures outside this
range may adversely affect the drives ability to meet specifications. To confirm that the required cooling for the electronics
and HDA case is provided, place the drive in its final mechanical configuration, perform random write/read operations and
measure the HDA case temperature after it has stabilized.

b. Non-operating

–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 68°F (20°C) per hour. This specification
assumes that the drive is packaged in the shipping container designed by Seagate for use with drive.

6.4.2

Relative humidity

The values below assume that no condensation on the drive occurs.
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.

6.4.3

Effective altitude (sea level)

a. Operating

–1,000 to +10,000 feet (–305 to +3,048 meters)

b. Non-operating

–1,000 to +40,000 feet (–305 to +12,210 meters)
