Problems solved by technology

In such a system, if the hard disk is used as the storage medium to store some data continuously or irregularly, it will inevitably cause the hard disk to be in the power-on working state for a long time, or even work uninterruptedly for 24 hours.
Such a working state seriously violates the basic working requirements of the hard disk, resulting in a sharp shortening of the life of the hard disk and low reliability of the storage system.

Embodiment Construction

[0038] The invention relates to data storage technology in the field of data communication, and provides a multi-level buffer storage system and method. The storage system and method provided by the present invention are mainly applied to occasions where the amount of data storage is not large. It can effectively prolong the service life of the hard disk and increase the stability and reliability of the system.

[0039] In order to make the purpose, 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, but not to limit the present invention.

[0040] Referring to FIG. 1 , it is a schematic structural diagram of an embodiment of the storage system of the present invention. The system includes a primary storage unit 1 , a s...

Abstract

The invention relates to the storage technique in the filed of data communication, using multi level buffer storage system. The said system comprises a first storage unit, hard disk, control module, with the said first level storage unit being disk buffer area for writing and reading of data temporarily with the said control module used for controlling the reading and writing of the data, the secondary level storage unit writing the temporarily stored data of the first level storage unit based on the instruction of the control module, introducing the self stored data to the hard disk before the stored overall data arriving the preset valve value. It can increase the protection for hard disk, extending its usage, improving the reliability and stability of the storage system.

Description

technical field [0001] The invention relates to storage technology in the field of data communication, in particular to a multi-level buffer storage system and method. Background technique [0002] At present, because hard disks have many advantages such as mature technology, large storage capacity, and convenient application, many systems tend to use hard disks as the main storage medium to store various data of the system. [0003] As we all know, hard disks are high-precision devices, which have strict requirements and restrictions on the use environment and application methods. Ordinary civilian hard disks generally have a service life of about 20,000 hours. In general hard disk manuals, there are generally clear usage restrictions: the daily power-on time is no more than 10 hours, and the read and write duty cycle is less than 20%. In practical applications, the system often divides a part of the memory as the disk buffer of the hard disk or its equivalent devices (CFC...
