Embodiment Construction

[0037] 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.

[0038] see figure 1 , a solid state hard disk 100 is provided in the first embodiment of the present invention, comprising:

[0039] The detection module 10 is used to detect the occurrence of a small-scale write request of the solid-state hard disk;

[0040] A caching module 20, configured to cache the write request in memory;

[0041] The sending module 30 is configured to send the write request when the preset condition is met or the write request ends.

[0042] In this embodiment, the detection module 10 detects a small-range write request to the solid-state hard disk 100 , and the small-ran...

Abstract

The invention is applicable to the technical field of solid state disks, and provides a solid state disk and a method for optimizing a write request of the solid state disk. The method includes the steps: A, detecting the small-range write request of the solid state disk; B, caching the write request in a memory; C, issuing the write request when a preset condition is met or the write request is finished. Therefore, the write frequency of the solid state disk is effectively decreased, and the service life of the solid state disk is prolonged.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to a method for optimizing a write request of a solid-state hard disk and the solid-state hard disk. Background technique [0002] Since the SSD uses FTL (Flash translation layer, flash translation layer) to provide an address mapping table, that is, the mapping relationship between logical addresses and physical addresses, the number of erasing and writing of SSDs is limited. If the number of writes can be reduced under permitted conditions, it will be able to effectively prolong the life of the SSD. [0003] However, in the current prior art, there is no effective technology for reducing the number of write times in the solid-state hard disk, especially for the write times of small-scale write requests. [0004] To sum up, it can be seen that the existing solid-state hard disk structure obviously has inconvenience and defects in actual use, so it is necessary to im...
