A method, device, equipment and storage medium for erasing and writing data of a solid-state hard disk

Abstract

The embodiment of the invention discloses a data rewriting method, device, equipment and computer-readable storage medium of a solid-state hard disk. Wherein, the method includes that when the solid-state hard disk performs an erase operation or a write operation, within the corresponding fixed duration of the read operation or write operation, periodically monitor whether the currently executed operation is completed at regular intervals; if the currently executed operation has been completed, return A message that the operation has completed. The technical solution provided by this application adopts a timing detection method to timely judge whether the erasing or writing operation has been completed, optimize the erasing and writing operation of the solid-state hard disk, and judge the completion time of the erasing and writing operation in a timely and accurate manner, effectively avoiding invalid waiting time. Greatly improve the access rate of NAND, and then improve the performance of the overall solid-state drive, and enhance the competitiveness of the solid-state drive.

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
