Start/stop times
Power-on to ready time is based on typical operating conditions, default full current spin-up profile, and clean
shutdown prior to measurement. To ensure a clean shutdown a Flush Cache, Standby, or Standby Immediate
command must be completed before removal of interface power.

Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector.

Power consumption
Power requirements for the drives are listed in
drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.

An unexpected power loss event, spin up at cold or hot temperature extremes
may cause the drive to exceed the typical and max time to ready by 5 to 20
seconds. Extended time to ready is dependent on cache state and
environmental conditions prior to the unexpected power loss and during the
subsequent power on.
