Reducing current draw of solid state drives from a shared power supply of a computer at computer startup, each SSD including computer memory, a capacitor, a disk controller, and a charge controller, the disk controller configured to enable the charge controller to charge the capacitor upon receiving a charge command, the SSDs organized into startup groups characterized by a position in a predefined startup order. Upon startup of the computer, beginning with a first startup group in the predefined startup order and until the last startup group in the predefined startup order has received a charge command, embodiments include, sending, by a storage device initiator, a charge command to a startup group to initiate charging of the capacitor of each solid state drive in the startup group and waiting a predefined period of time before sending another charge command to a next startup group in the predefined startup order.
