Abstract

A data accessing method and a data accessing apparatus are provided. The method includes acquiring a size of a minimum access unit of a storage device; reading first data to be written into the storage device; determining whether a size of the first data is equal to an integer multiple of the size of the minimum access unit; and if the size of the first data is equal to an integer multiple of the size of the minimum access unit, storing the first data into the integer multiple of the minimum access unit in alignment; otherwise, adding padding data to the first data such that the size of the first data is equal to the integer multiple of the size of the minimum access unit, and storing the first data into the integer multiple of the minimum access unit in alignment.
