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
The present invention relates to field of data storage, particularly a kind of method and electronic equipment of storing data.
Background technology
SSD (Solid State Disk, solid state hard disc) is the hard disk made from solid-state electronic storage chip array, is made up of control module and storage unit.Compared with the mechanical hard disk of solid state hard disc and same capacity, there is the advantages such as volume is little, lightweight, noiselessness, and Lu is more durable, more low temperature, antidetonation, more portable more, is therefore widely used in the fields such as military affairs, vehicle-mounted, industry control, video monitoring, electric power, medical treatment, dirty sky.
The storage medium of solid state hard disc is divided into two kinds, and one is to adopt flash memory FLASH chip as storage medium, and another is to adopt dram chip as storage medium.The advantage of the solid state hard disc maximum based on flash chip can move exactly, and Lu's data protection is not subject to power supply control, can be adapted to various environment.Solid state hard disc based on dram chip needs independent current source to carry out protected data safety, and range of application is narrower, belongs to non-mainstream equipment.
Solid state hard disc based on flash chip generally includes: SLC (Single-Level Cell, single-layer type stores people MLC (Multi Level Cell, multiple field stores) and TLC (Trinary-Level Cell, three-layer type stores LSLC and stores 1 bit data in each unit, approximately 100,000 erasing and writing lifes.MLC is in each unit storage two bits, and packing density is larger, approximately 10,000 erasing and writing lifes.TLC is in each cell stores 3 bit data, with low cost many, but the slow life-span of speed is short, approximately 500 erasing and writing lifes.
Along with a large amount of former times of TLC and, the life problems of TLC becomes a large bottleneck of SSD gradually.At present, existing a solution is that control chip reduces the unnecessary amount of writing.As, the solid state hard disc of a 12OG, the file that control chip makes to write 12OG just calculates that to do flash memory completely once erasable, and still, this scheme can not solve TLC and write lower root problem of life-span.Also have a solution be by data buffer storage in internal memory, still, the problem that when this scheme exists system exception, in internal memory, the data of buffer memory can be lost.
Summary of the invention
The invention provides a kind of method and electronic equipment of storing data in order to extend the serviceable life of SSD.Described technical scheme is as follows:
On the one hand, the invention provides a kind of method of storing data, be applied to an electronic equipment, described electronic equipment is connected with hard disk drive HDD and solid-state hard disk SSD, and described method comprises:
