Abstract
Systems and methods for early warnings of power loss in solid state storage drives are disclosed. Early warnings of power loss can be used to power the drive to force the drive into a low power states before the energy in backup power sources, such as backup capacitors, is used. The low power states can allow for the reduction of power use by the drive which can provide cost savings and reduction in the risk that the drive will be rendered reconfigurable by a power failure event.
