Problems solved by technology

In order to improve the system data access speed, more and more applications use solid-state drives to replace traditional mechanical hard drives, but the faster the data is read and written, the more the loss of solid-state drives will be aggravated
[0003] In summary, the existing SSD data caching technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Embodiment Construction

[0059]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] see figure 1 , in the first embodiment of the present invention, a caching system 100 for solid-state disk data is provided, including:

[0061] Divide module 10, be used for setting the part memory of system memory as the data cache area of ​​solid-state hard disk;

[0062] The caching module 20 is configured to cache the read-write data of the solid-state hard disk in the data cache area of ​​the solid-state hard disk.

[0063] In this embodiment, through the division module 10 in the caching system 100 of solid-state hard disk data, part of the memory in the memory system of the computer...

Abstract

The invention is applied to the technical field of storage, and provides a method and system for data caching of a solid state disk. The method for the data caching of the solid state disk comprises the following steps: setting a part of memory of a system memory as a data buffer cache of the solid state disk; caching read and write data of the solid state disk into the data buffer cache of the solid state disk. Therefore, the method and system of the data caching of the solid state disk reduces the visit times of the solid state disk and lengthens the service life of the solid state disk.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method and system for caching solid state hard disk data. Background technique [0002] SSD (Solid State Disk, solid state disk), that is, IDE FLASH DISK is a hard disk made of solid-state electronic storage chip array, which consists of a control unit and a storage unit (FLASH chip). The interface specifications and definitions, functions and usage methods of SSDs are exactly the same as those of ordinary hard disks, and the product shape and size are also completely consistent with ordinary hard disks. Widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields. The characteristics of the Flash medium of the solid-state hard disk determine: 1) The reading and writing of the Flash is in units of pages; 2) The number of erasing and writing of the Flash...
