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.
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.
