Abstract: A data storage system with intelligent power management includes a plurality of data storage devices and a controller. Each data storage device is capable of operating in one of (N+1) power saving functions where N is an integer larger than 1. The (N+1) power saving functions sequentially correspond to from the 0th to the Nth power saving levels. The controller reads a user-setting power saving level (I) where I is an integer index ranging from 0 to N. The controller reads a current power saving level (J) of a current power saving function of one of the plurality of data storage devices where J is an integer index ranging from 0 to N. The controller controls said one data storage device to operate in one power saving function among the (N+1) power saving functions according to the user-setting power saving level (I) and the current power saving level (J).
