Abstract
A method for controlling data write operation of a mass storage device is provided. The mass storage device has a controller and a memory unit. The method includes connecting the mass storage device to a host device, and receiving a voltage provided from the host device; sensing and monitoring whether the voltage is lower than a first predefined voltage; writing data to the mass storage device with a first frequency when the sensed voltage is higher than the first predefined voltage; and writing data to the mass storage device with a second frequency when the sensed voltage is lower than the first predefined voltage, wherein the second frequency is adjusted by decreasing the first frequency.
