Data processing method and device for solid state disk

Abstract

The embodiment of the invention provides a data processing method and device for a solid state disk, which are used for predicting I / O (Input / Output) information in a first time period in the future according to a prediction model so as to execute active management on the solid state disk according to a prediction result and reduce the operation response time of a host side. The method provided bythe embodiment of the invention comprises the following steps: predicting I / O information in a future first time period through a prediction model, wherein the I / O information at least comprises an I / O type and / or I / O intensity; and performing active management on the solid state disk according to the prediction result so as to reduce the operation response time of the host.

Description

technical field [0001] The invention relates to the technical field of data processing of solid-state hard disks, in particular to a data processing method and device for solid-state hard disks. Background technique [0002] In the SSD solid-state hard disk, the read-write cache buffer of the SSD is relatively small, generally ranging from a few MB to tens of MB. Due to the asymmetry between the bus bandwidth of the SSD interface and the storage speed of the SSD solid-state hard disk, the internal disk Buffer often becomes the bottleneck of write performance. [0003] Therefore, how to implement the management of the SSD, reduce the response time of the host client operation, effectively allocate limited hardware resources, and better utilize the master control performance of the SSD is a problem that needs to be solved urgently. Contents of the invention [0004] An embodiment of the present invention provides a data processing method and device for a solid-state hard di...
