[. . . ] C 6. 3 Power dissipation 25 ST336704FC Typical power dissipation under idle conditions is 12. 0 watts (40. 95 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 7). 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. 1. 800 1. 600 1. 400 19 17 15 Watts 0. 800 0. 600 0. 400 0 50 100 150 200 250 I/Os per Second Figure 7. input/output operations per second 5V A 12V A Watts Amperes 1. 200 1. 000 13 11 ST318304FC Typical power dissipation under idle conditions is 9. 6 watts (32. 76 BTUs per hour).

C 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 With cooling designed to maintain the case temperatures of Table 2, 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. The enclosure for the drive should be designed such that the temperatures at the locations specified in Table 2 are not exceeded. Air flow may be needed to achieve these temperature values (see Section 8. 4 and 8. 4. 1). Operation at case temperatures above these values may adversely affect the drives ability to meet specifications. The MTBF specification for the drive is based on operating in an environment that ensures that the case temperatures specified in Table 2 are not exceeded. Occasional excursions to drive ambient temperatures of 131°F (55°C) or 41°F (5°C) may occur without impact to specified MTBF. Air flow may be needed to achieve these temperatures (see Section 8. 4. 1). Continual or sustained operation at case temperatures above these values may degrade MTBF. To confirm that the required cooling for the electronics and HDA is provided, place the drive in its final mechanical configuration, perform random write/read operations. After the temperatures stabilize, measure the case temperature of the components listed in Table 2 (see note [2]).
