Data feature-based solid state disk (SSD) acceleration system realization method

Abstract

The invention discloses a data feature-based solid state disk (SSD) acceleration system realization method. The method comprises the steps of writing data to an SSD; and after the data is written to the SSD, adding a data feature through a custom command provided by the SSD, wherein the data feature is used for marking whether the data is pre-read or not, a pre-reading range and relevance. According to the method, the data range needed to be quickly read in an SSD memory is marked to a certain extent, and the SSD actively reads next data in the marked range to a data buffer area when the data in the marked range is read subsequently, so that the situation that data reading continuity is interrupted is avoided, the acceleration effect is achieved, a multi-task and multi-thread pre-reading mechanism can be realized, the system throughput is increased to the maximum extent, and the performance of the SSD system is improved.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to an implementation method of a solid-state hard disk SSD acceleration system based on data characteristics. Background technique [0002] The implementation method of the existing solid-state disk SSD acceleration system generally relies on reading data to the data buffer of the solid-state disk SSD, and then directly reads the data from the data buffer of the SSD to accelerate the system, but the existing The implementation method of the solid-state hard drive SSD acceleration system generally only works when reading sequentially, and it cannot play the role of pre-reading if the sequentiality is not so strict, or when reading is interrupted by other commands. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for realizing an SSD acceleration system based on data characteristics. [0004] The ob...
