Abstract

The invention is applicable to the technical field of solid-state hard disk control and provides a method for dynamically adjusting a reserved space of a solid-state hard disk and the solid-state hard disk. The method comprises the steps of monitoring, i.e. monitoring the use situation of the memory space of the solid-state hard disk; warning, i.e. giving out warning information when the use rate of the memory space reaches a preset warning threshold; control, i.e. according to the control command of a user, adjusting the warning threshold of the use rate of the memory space of the solid-state hard disk or controlling write I/O (Input/Output) to be written in the solid-state hard disk. Therefore, by adopting the method, the goal of dynamically keeping the performance of the solid-state hard disk is realized and the service life of the solid-state hard disk is prolonged.

Description

technical field [0001] The invention relates to the technical field of solid-state storage, in particular to a method for dynamically adjusting the reserved space of a solid-state hard disk and the solid-state hard disk. Background technique [0002] In the existing computer or storage system, the feature of the solid-state hard disk is that the unit of reading and writing is a page, and the unit of erasing is a block. Solid-state drives will get slower and slower as they are used, which has a lot to do with the working principle of solid-state drives. Solid-state drives use flash memory as a storage medium, and the feature of flash memory is that data must be erased before it can be written again. This is different from mechanical hard drives, which can directly overwrite and write data. [0003] The feature of solid-state drives has caused a lot of trouble for existing file systems. When new data is written and old data needs to be replaced, the SSD (Solid State Disk, so...
