Abstract

A data reading and writing method includes: after a first electronic device establishes 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, in the first usage mode, the second electronic device being configured to transmit a first part of target data between the first storage component and the third electronic device; 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; and after completing the target data reading/writing task, controlling the first storage component to switch back to a second usage mode.

Dependent claims

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.

A control method applied to a third electronic device, comprising:

after obtaining an operation of establishing a first communication connection between a first electronic device and a second electronic device, sending an obtained target data reading/writing task to the first electronic device and the second electronic device to cause a first storage component of the first electronic device to switch to a first usage mode, 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, a first part of the target data being a part of the target data required by the target data reading/writing task;
and
reading or writing a second part of the target data in a second storage component of the first electronic device using a second communication connection with the second storage component, the second part of the target data being a remaining part of the target data after removing the first part of the target data.

A data reading and writing system comprising:

a first electronic device, the first electronic device having a first storage component and a second storage component;
and
a second electronic device, the second electronic device being configured to establish a first communication connection with the first electronic device, and establish a data transmission channel with the first storage component, wherein:
when a target data reading/writing task is obtained from a third electronic device, the first storage component only has a data transmission channel with the second electronic device to transmit a first part of target data between the first storage component and the second electronic device through the second electronic device, the first part of the target data being a part of the target data required by the target data reading/writing task;
the first electronic device is configured to establish a first communication connection with the third electronic device to transmit a second part of target data between the second storage component 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, the first electronic device is configured to control the first storage component to only have the data transmission channel with the first electronic device.
