1. A data reading and writing method comprising:
after a first electronic device establishing a first communication connection with a second electronic device, controlling a first storage component of the first electronic device to switch to a first usage mode in response to obtaining a target data reading/writing task from a third electronic device, the first storage component only having a data transmission channel with the second electronic device in the first usage mode to cause the second electronic device to transmit a first part of target data between the first storage component and the third electronic device, the first part of the target data being a part of the target data required by the target data reading/writing task;
transmitting a second part of the target data between a second storage component of the first electronic device and the third electronic device using a second communication connection between the first electronic device and the third electronic device, the second part of the target data being a remaining part of the target data after removing the first part of the target data; and
after completing the target data reading/writing task, controlling the first storage component to switch back to a second usage mode, the first storage component only having the data transmission channel with the first electronic device in the second usage mode.
