Moreover, if the data is classified into types, each write command of the system needs to be distinguished, and the type of garbage collection and all related modules involved in all instructions need to be divided into two categories, which consumes a lot of system management resources. For consumer-grade solid-state drives, the cost performance will be reduced, and the competitiveness will be reduced

Abstract
The present application provides a data storage method and device, the method comprising: acquiring data to be stored; if the data to be stored is system data, determining the first core unit and the second core unit used to store the data to be stored in the solid state hard disk Two core units, the first core unit and the second core unit are different core units; storing the system data in the first physical block of the first core unit and the second core unit respectively in the second physical block. Through the technical solution of the present application, there is no need to use a fixed area to store system data, avoiding the waste of space in the fixed area and the waste of system resources.
Description
technical field [0001] The present application relates to the field of storage technology, in particular to a data storage method and device. Background technique [0002] Solid State Drives (SSD) is a new type of hard disk with fast speed, high shock resistance, good stability, high integration, large capacity, fast read and write speed, small read and write delay, low power consumption, Features such as non-volatile storage media are widely used in various fields of life. For example, consumer electronics, military equipment, surveillance security, network, server, handheld device, industrial control, etc. [0003] During the use of the SSD, data can be continuously written to a physical block (Block, also called a data block) until the physical block is full, and then data is written to the next physical block, and so on. Further, in the process of using the SSD, in order to ensure that there are available physical blocks, the effective physical block can also be garbag...
