Method and device of storing data object

A device of storing a data object, the device comprising:

• memory storing computer-executable instructions;
• and
• a processor configured to execute the computer-executable instructions such that the processor is configured to,
• divide data of a data object into a first part of data and a second part of data, in response to receiving a writing request for a data object,
• write the first part of data into a first data file stored in a first external storage device, and
• write first location information and the second part of data into a second data file stored in a second external storage device,
• the first part of data including a data field of the data object,
• the second part of data including a meta data of the data object,
• the first location information including location information of the first part of data within the first external storage device.

A non-transitory computer readable storage medium storing computer-executable instructions that, when executed by a processor, cause the processor to perform operations including:

• dividing data of a data object into a first part of data and a second part of data, in response to receiving a writing request of a data object, the first part of data including a data field of the data object, the second part of data including a meta data of the data object;
• writing the first part of data into a first data file stored in a first external storage device;
• and
• writing location information of the first part of data in the first external storage device and the second part of data into a second data file stored in a second external storage device.
