A data storage device includes a non-volatile memory device, a capacitor bank, and a power regulator electrically coupled to the capacitor bank and configured to provide power to the non-volatile memory device. The data storage device further includes a controller configured to discharge the capacitor bank from a first voltage to a second voltage at a first constant current and determine a first discharge time, controller is further configured to discharge the capacitor bank from the first voltage to the second voltage at a second constant current and determine a second discharge time. A voltage holdup time of the capacitor bank is then determined based on at least the first discharge time and the second discharge time.
