2.7 Power specifications The drive receives DC power (+3.3V) through the ZIF connector (CE-ATA interface). 2.7.1 Power consumption Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on an average of drives tested, under nominal conditions, using +3.3V input voltage at 25°C ambient temperature. • Startup mode Startup power is measured from the time of power-on to the time that the drive spindle reaches operating speed. • Seek mode During see

2.7.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +3.3 volt line. Using 3.3-volt power, the drive is expected to operate with a maximum of 70 mV peak-to-peak square-wave injected noise at up to 20 MHz. Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current. 2.7.3 Voltage tolerance Voltage tolerance (including noise): 3.3V ± 5% Lyrion CE-ATA Product Manu

2.8 Environmental specifications 2.8.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 70°C (158°F) within the operating ambient conditions. Case temperature of the drive operating at 60°C ambient may hit a maximum of 70°C at certain parts of the casing. Above 1,000 feet (305 meters), the maximum operating temperature is derated linearly by 1°C every 1000 feet. Operating
