Abstract

The embodiment of the invention discloses a data storage method, device and equipment for a solid state drive and a computer readable memory medium. The method comprises the steps of storing change quantity of management data to first storage areas when the management data of LBAes is changed in a solid state drive operation process; copying the management data corresponding to the LBAes from DDR(Double Data Rate) to second storage areas corresponding to the LBAes according to preset data copy quantity when residual space of the first storage areas of the LBAes satisfy a preset condition, andsending a notice for flashing data in the first storage areas and the second storage areas of the LBAes to an NAND management module; and flashing the data in the first storage areas and the second storage areas of each LBA to the NAND when the solid state drive is powered off, and flashing L2P tables of the updated management data to a control manager, wherein the data in each LBA is obtained bypre-dividing the management data of the solid state drive according to preset data storage quantity. According to the method, the device, the equipment and the computer memory medium, the data quantity needing to be stored when the SSD is powered off is reduced, and the data integrity in the SSD is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of solid-state hard disk data storage, and in particular, relate to a data storage method, device, device, and computer-readable storage medium of a solid-state hard disk. Background technique [0002] With the rapid development and widespread application of computer technologies such as the Internet, cloud computing, and the Internet of Things, massive amounts of data will be generated all the time in daily work or life that needs to be processed and stored. The explosive growth of data and the security of users for data The increase in requirements and the rapid development of information technology have put forward higher requirements for the performance of the storage system. [0003] SSD (Solid State Drives, solid state drive), also known as solid disk, is a hard disk made of solid state electronic memory chip array, which consists of a control unit and a solid state storage unit. ...
