Problems solved by technology

[0004] However, in practical applications, due to the limited computing power of the control unit and the limited storage space of the storage unit of the SSD, the mapping tables and cache data that can be stored are usually relatively small, which will affect the hit rate of data in the cache , at the same time, due to frequent switching in and out of its mapping table, it will cause delays in read and write access of solid state drives, thus affecting user experience

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] In practical applications, when a host accesses a solid-state drive, it usually needs to read the mapping table stored in the memory of the solid-state drive one or more times to accurately obtain the required data. However, the current controller of the solid-state drive has relatively poor computing power. Moreover, its memory space is not large, so the mapping table and cached data stored in the memory of the solid-state hard disk are limited. As a r...

Abstract

The invention provides an information adjusting method and electronic equipment. When an information adjusting request is detected, a corresponding moving instruction is triggered based on the information adjusting request, and therefore target information between a target solid hard disk and a host is moved. The target information can be assisted by the host in processing reading and writing commands. It is clear that by means of the mode that the target information is dynamically adjusted between the solid hard disk and the host, the host can read needed data from internal storage of itself, the response burden of the target solid hard disk to the reading and writing commands of the host is relieved, reasonable distribution of resources is achieved, and the work efficiency is greatly improved.

Description

technical field [0001] This application mainly relates to the application field of solid-state hard drives, and more specifically relates to an information adjustment method and electronic equipment. Background technique [0002] Solid State Drives (SSD) are hard disks made of solid-state electronic storage chip arrays. They are composed of a control unit and a storage unit. In practical applications, they use NAND Flash as a storage medium, which has fast read and write speeds and shock resistance. With the advantages of good drop resistance, low power consumption, no noise, wide operating temperature range and light weight, it is widely used in military, vehicle, industrial control, aviation, electric power and medical fields. [0003] Among them, since the solid-state hard disk cannot be rewritten directly, it needs to be erased before writing, so the Flash Translation Layer (Flash Translation Layer, FTL) is needed for data management, and the underlying information is hi...
