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.
 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.
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.
