1. A method for managing power, comprising the steps of:

  • measuring current used to power the devices;

    based on the measured current, profiling a plurality of devices to determine a current profile for each individual device of the plurality of devices;

    based on the current profile of each individual device, determining at least one of a plurality of possible time thresholds of when each individual device goes from a high current region to at least one of a plurality of possible low current regions; and

    wherein the current profile of at least one of the individual drives comprises at least three successive current regions which decrease over time with at least two of the three current regions being associated with drive spin-up.
