Spin-Up Time S.M.A.R.T. parameter indicates an average time (in milliseconds or seconds) of spindle spinup (from zero RPM (Revolutions Per Minute) to fully operational).
The low value means it takes too long for the hard disk to a fully operational state.
This parameter is considered informational by the most hardware vendors. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure. Regular backup is recommended. Pay closer attention to other parameters and overall drive health.
