Problems solved by technology

For example, for a 12OG solid-state hard drive, the control chip makes the file written in 12OG count as a flash memory completely erased once, but this solution cannot solve the fundamental problem of the low writing life of TLC
Another solution is to cache the data in the memory, but this solution has the problem that the data cached in the memory will be lost when the system is abnormal

Abstract

The invention discloses a data storage method and an electronic device and belongs to the field of data storage. The data storage method is applied to the electronic device, and the electronic device is connected with an HDD (hard disk drive) and an SSD (solid state drive). The data storage method includes respectively caching data to be stored into an internal memory and the HDD of the electronic device; writing the data stored in the internal memory into the SSD when the electronic device is normally shut down; acquiring the data from the HDD and writing into the SSD when the electronic device is abnormal. The electronic device comprises a cache module and a storage module. Accordingly, erasing and writing times of the SSD is decreased, service life of the SSD is prolonged, and safety and reliability of data storage are effectively improved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data storage method and electronic equipment. Background technique [0002] SSD (Solid State Disk) is a hard disk made of an array of solid-state electronic storage chips, consisting of a control unit and a storage unit. Compared with mechanical hard drives of the same capacity, solid-state drives have the advantages of small size, light weight, and no noise, while Lv is more durable, lower temperature, more shock-resistant, and more portable, so it is widely used in military, vehicle, industrial control, video surveillance, Power, medical, air and other fields. [0003] There are two types of storage media for solid-state hard disks, one is to use flash memory FLASH chips as storage media, and the other is to use DRAM chips as storage media. The biggest advantage of solid-state drives based on flash memory chips is that they can be moved, and LV data protection is not controlled ...
