A data storage device, comprising:

• a memory device including a plurality of first data areas and a temporary data area, each first data area and the temporary data area including memory cells structured to store data;
• a buffer memory coupled to the memory device and configured to temporarily store the data received from a host before writing the data to the plurality of first data areas or the temporary data area;
• and
• a memory controller configured to receive a first write request for writing the data and consecutive logical addresses from the host and write, upon occurrence of a trigger event that requires the data to be written to the memory device, the data to either the temporary data area or a first data area selected based on first data area information included in the first write request, depending on whether a size of the data is less than a preset reference size.
