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.

Abstract: A data query method and apparatus are disclosed. The method includes: determining a target directory block including m directory entries and m file names, where the m directory entries one-to-one correspond to the m file names, and the m directory entries and the m file names are sequentially arranged according to a preset rule; determining a current first set and a current second set based on a binary search algorithm and the target directory block; determining a first common prefix between a to-be-accessed file name and a file name in the current second set; comparing the to-be-accessed file name with a third file name character by character from a first character after the first common prefix; and if the to-be-accessed file name is the same as the third file name, obtaining data of a to-be-accessed file based on a directory entry corresponding to the third file name.

Abstract: Embodiments relate to the field of storage technologies. The method is applied to a flash device whose first physical storage space stores a data block at a first security level and a data block at a second security level and whose second physical storage space stores a data block at a second security level. The method includes: receiving a data write request used to request to write target data, and obtaining a security level of the target data; and writing the target data into the first physical storage space if the security level of the target data is the first security level; or writing the target data into the second physical storage space or writing the target data into the second physical storage space and the first physical storage space if the security level of the target data is the second security level.
