Data storage device which can be controlled remotely and remote control system

The invention provides a remote control system, which comprises a cloud management platform and an electronic apparatus. The electronic apparatus comprises a data storage device and a motherboard. The data storage device comprises a data storage unit and a program execution management unit. The program execution management unit comprises a microprocessor. The data storage device is connected a powered device module. The powered device module is able to provide a Ethernet power to the data storage device. When the electronic apparatus is in a power-off state, the data storage device can maintain a normal operation via the Ethernet power, and therefore is allowed to be controlled by the cloud management platform, so that the cloud management platform can control an operation of the data storage device at any time.
