Abstract

The invention discloses a method and system for dynamically adjusting solid state disk garbage collection parameters. The method comprises: A. acquiring the predicted length of idle time of a solid state disk; B. setting the garbage collection parameters of the solid state disk according to the predicted length of idle time of the solid state disk; C. executing the solid state disk garbage collection operation according to the garbage collection parameters within the predicted length of idle time of the solid state disk. The method and the system in the invention improve the solid state disk garbage collection efficiency as well as response speed and read-write performance of the solid state disk in operation.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for dynamically adjusting garbage collection parameters of a solid-state hard disk and a system thereof. Background technique [0002] With the rapid development of computer technology, computer storage media has also made great progress. Developed from ordinary hard disk to SSD (Solid State Disk, solid state disk). Because SSDs do not use the mechanical rotation mechanism of ordinary hard disks, they are extremely shock-resistant. The storage module of the solid-state hard disk is a semiconductor flash memory NAND Flash chip. The NAND Flash chip operation unit is generally divided into two levels: block (block) and page (page). The size of the page is 1KB, 2KB, 4KB, 8KB, etc., and with the development of the manufacturing process, there is a tendency to increase; each block generally contains 16, 32, 64 or more pages. There are three operations for NAND particles: 1. Read a...
