Power Management Settings

SettingDescription
HDD StandbySelect a value from the dropdown list of options or leave it set to the default Always On. This specifies the minutes of inactivity before the drive enters standby mode. For information on identifying spun-down drives, see this forum post. Temperature monitoring is disabled for standby disks.
Advanced Power Management (APM)Sets the APM level that controls power management behavior when drives are idle, not maximum performance capabilities. When drives are actively accessed, they operate at full performance regardless of the APM setting. Lower-numbered levels prioritize power savings during idle periods, while higher levels prioritize quick response times. Power management profile options:
  • Disabled (the default setting)
  • Level 1 - Minimum power usage with Standby (spindown)
  • Level 64 - Intermediate power usage with Standby
  • Level 127 - Maximum power usage with Standby
    <liLevel 128 - Minimum power usage without Standby (no spindown)
    <liLevel 192 - Intermediate power usage without Standby
    <liLevel 254 - Maximum performance, maximum power usage
