Abstract

The embodiment of the invention discloses a data storage method and device, which are applied to a terminal. The terminal includes at least one disk. The disk is divided into a plurality of virtual storage segments according to physical addresses, and physical address ranges corresponding to the plurality of virtual storage segments do not coincide. The method includes: receiving a storage request for to-be-stored data, determining a target virtual-storage-segment, which is used for storing the to-be-stored data, according to an identifier of a target file corresponding to the to-be-stored data and information stored in metadata storage segments; obtaining a last storage location of data stored in the target virtual-storage-segment, and determining that the obtained storage location is an initial storage location of the to-be-stored data, and from the initial storage location, starting to store the to-be-stored data. By applying the embodiment of the invention to store the data, seek time is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data storage method and device. Background technique [0002] Currently, computers read and write data in files in the order of physical addresses on the disk. However, as the number of files stored on the disk increases, a large number of files will be migrated and deleted, resulting in a fragmented distribution of the storage space of the disk. At this time, if the computer needs to store data again, for example, when storing the target data, it needs to search for free storage space in the disk according to the order of physical addresses, and judge whether the free storage space can store the above target data, if not, then It is necessary to search for free storage space again to find free storage space capable of storing the target data and store the target data. [0003] When storing data according to the above method, not only need to search for free storage space a...
