Data erasing method, apparatus and device for solid-state hard disk and storage medium

Abstract

The embodiment of the invention discloses a data erasing method apparatus and device for a solid-state hard disk and a computer-readable storage medium. The method comprises the following steps: whenerasing operation or writing operation is performed on the solid state disk, whether the currently executed operation is completed or not is monitored every interval of time in a fixed period of timecorresponding to the read operation or the write operation respectively; a message that the operation has completed is returned if the currently executed operation has completed. The technical schemeprovided by the application adopts a timing detection mode, judges whether the erase or write operation has been completed in time, optimizes the erase and write operation of the solid state disk, judges the completion time of the erase and write operation timely and accurately, effectively avoids the invalid waiting time, greatly improves the access speed of the NAND, further improves the performance of the whole solid state disk, and enhances the competitiveness of the solid state disk.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data storage, and in particular, relate to a data erasing method, device, equipment, and computer-readable storage medium of a solid-state hard disk. Background technique [0002] With the rapid development and widespread application of computer technologies such as the Internet, cloud computing, and the Internet of Things, massive amounts of data will be generated all the time in daily work or life that needs to be processed and stored. The explosive growth of data and the security of users for data The increase in requirements and the rapid development of information technology have put forward higher requirements for the performance of the storage system. [0003] SSD (Solid State Drives, solid state drive), also called solid disk, is a hard disk made of solid-state electronic storage chip array, which consists of a control unit and a solid-state storage unit (FLASH chip or DRAM c...

Problems solved by technology

In the prior art, the erasing and writing operation time is preset for a specific time. It may appear that the erasing operation has been completed, or the writing operation has been completed, but the preset time has not yet arrived, and it is still necessary to wait until the preset time arrives. cause waste of resources
