6.4Environmental 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). Above 1,000 feet (305 meters), the maximum tem- perature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

6.4.1Temperature

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 50°C. Occasional excur- sions 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 36°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 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.

6.4.2Relative 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.
