Abstract
A file merging method performed by a controller in a storage system includes reading a first file and a second file on a solid state disk, determining whether a key of the first data is the same as a key of the second data, creating a third file on a mechanical hard disk when the key of the first data is the same as the key of the second data, merging the first data and the second data, and writing the merged data into the third file.
