Deferred spinup

Momentus Thin drives do not support the deferred spinup option. If you require this option, refer to the Momentus 5400.3 SATA Blade
Server family of drives.

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