Abstract: A storage system, a file storage and reading method, and a terminal device are provided. A storage system including a UFS is used as an example. The storage system configures different medium forms of the UFS, for example, configures persistent storage space of the UFS including SLC and TLC medium forms, to implement hybrid medium multi-disk storage. Based on the storage system, a hot file related to an application running rate is preferentially selected and stored in an SLC storage area of the UFS, and files on a mapped multi-disk are mounted on a same directory of a file system, so that files can be migrated between the SLC storage area and a TLC storage area without user perception, to improve performance of the storage system.
