3.9.1.1 Typical current profile

3.9.2 Deferred spinup

Momentus Thin drives do not support the deferred spinup optio

n. If you require this option, refer to the Momen-

tus 5400.3 SATA Blade Server family of drives.

3.9.3 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 30 MHz.

Note. Equi

valent resistance is calculated by dividing the nominal voltage by the typical RMS read/write

current.

3.9.4 Voltage tolerance

Voltage tolerance (including noise):

5V ±

10%
