Abstract

The invention discloses a hierarchical storage system and a method, belonging to the technical field of solid state hard disk. The system includes a first storage unit and a second storage unit. The first memory unit includes a memory space and a memory controller. The memory controller comprises a data acquisition module for acquiring data files inputted by a user; the encryption module is used for encrypting the data file, and the encrypted data file is cached in the storage space. A hierarchical storage module, configured to divide the data files cached in the storage space into storage types, the hierarchical storage module retaining the data files having the first storage type in the storage space and saving the data files having the second storage type in the second storage unit; thefirst storage unit is a PCIe solid state disk. The technical proposal has the advantages of reducing the use cost of the solid-state disk, improving the read-write performance of the hard disk, and thus improving the user experience.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to a hierarchical storage system and method. Background technique [0002] As an emerging storage medium, solid state drives (SSD) have faster read and write speeds, lower shock resistance, lower power consumption, and lower operating noise than traditional mechanical hard drives. The operating temperature range is wider, and the shape is thinner and lighter than traditional mechanical hard drives. Therefore, with the development of storage technology, more and more storage solutions are implemented using solid-state drives. [0003] In the prior art, usually only one kind of hard disk is used to store data, for example, solid-state hard disk is used to store data, but the types of these data are different, and the frequency of being read is also different, and the uniform use of solid-state hard disk to store data is not conducive to data collection. The reading an...
