STORAGE DEVICE AND ELECTRONIC DEVICE MANAGING DATA TRANSMITTED TO STORAGE DEVICE

An electronic device includes a memory and a processor. The memory stores first data with regard to a first position of a data area of a storage device and second data with regard to a second position of the data area. When a size of the first data included in a first page is smaller than a reference size and a size of the second data included in a second page different from the first page is smaller than the reference size, the processor outputs data blocks including the first data and the second data, and outputs first metadata about the first position with regard to the first data and second metadata about the second position with regard to the second data. A size of the data blocks is smaller than a sum of a size of the first page and a size of the second page.
