Abstract

The invention discloses a method, device and equipment for improving SSD full-disk scanning efficiency and a medium. The method comprises the following steps that a plurality of Overlapped resources are defined; the Overlapped resources are initialized; whether a to-be-sent read command exists or not is judged; if yes, whether idle Overlapped resources exist in the plurality of Overlapped resources or not is judged; if yes, a reading command is sent through the idle Overlapped resources; and waiting for idle Overlapped resources is executed after the reading command is sent. According to themethod, a multi-thread function is replaced, an Overlapped I/O model is an OS (Operating System) for transmitting data to a user, context switching is completed, and the user is informed after processing is completed. Processing in a program is changed into processing of an OS, and the interior of the program is also processed by a thread. The method can greatly reduce the development difficulty,improve the development efficiency and reduce the software maintenance cost.

Description

technical field [0001] The present invention relates to a solid-state hard disk, more specifically to a method, device, device and medium for improving the efficiency of SSD full-disk scanning. Background technique [0002] In recent years, SSD (Solid State Disk, solid state drive) products have achieved unprecedented development due to their high-speed read and write performance. Many manufacturers have invested a lot of manpower and energy in making SSD products, and the performance requirements for SSD High, in order to ensure the quality of the product, it needs to go through a series of tests and verifications. Among them, full disk scan or disk scan of a specified storage range is one of the tests, and usually requires a certain amount of time for the test. [0003] It is not complicated to implement a full disk scan of SSD, as long as the NVMe (Non-VolatileMemory express) read command is sent according to the protocol. The performance of the SSD comes into play. Us...
