2.9.1 Power consumption Power requirements for the drives are listed in the table on page 7. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed. • Seek mode During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does

In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary. 2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum
