[. . . ] Typical power dissipation under idle conditions is 10. 75 watts (36. 68 BTUs per hour) during 2 Gbit operation. To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 2). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3. 4123.

D 27 6. 4 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). Maximum wet bulb temperature is 82°F (28°C). Operating The maximum allowable continuous or sustained HDA case temperature for the rated MTBF 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 specified MTBF. Continual or sustained operation at HDA case temperatures outside these limits may degrade MTBF. 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. 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. HDA Temperature Check Point 0. 5" Figure 4.
