Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave
injected noise at up to 10 MHz.
injected noise at up to 10 MHz.
Note.
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.

Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
Actual drive case temperature should not exceed
Actual drive case temperature should not exceed
65°C (149°F) within the operating ambient conditions.
Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet.
