A data storage device access method, a device and a system. The method includes receiving a mode switch control command by a first bus through a first interface of the control device; switching a second interface of the control device to a predetermined mode based on the received mode switch control command. In cases where the second interface is switched to the first mode in accordance with the mode switch control command, the other device connected to a second bus corresponding to the second interface, accesses the data storage device under the control of the control device via the second interface through the second bus. In cases where the second interface is switched to the second mode in accordance with the mode switch control command, the other device directly accesses the data storage device through the second bus without the control of the control device.
