Description

Behavior test method and device of SSD in idle state, computer equipment and storage medium

Technical Field

The invention relates to the technical field of solid state disk testing, in particular to a behavior testing method and device of an SSD in an idle state, computer equipment and a storage medium.

Background

At present, most PCIeNMeSSD (hereinafter referred to as SSD) has the characteristic of entering a non-working state; generally, when the SSD is idle and the idle time exceeds 2 seconds, for a Windows10 operating system (hereinafter referred to as a system), the system issues an NVMeSetFeature (NVMe set function) command to the SSD, so that the SSD enters a non-working state, and then wakes up the SSD in the non-working state by issuing a release space command; in short, when the SSD is in the idle state, the system can roughly summarize its behavior as: the system issues an NVMeSetFeture command to enable the SSD to enter the non-working state → the system issues a space release command to enable the SSD to exit the non-working state.

For testing the SSD in the above scenario, a common method is to not perform any read/write operation on the SSD, i.e., directly make the SSD in an idle state. However, this test method, although simple, has the following drawbacks: 1) the SSD needs to be idle for more than 2 seconds, and the system can enable the SSD to enter a non-working state, so that the test coverage of the test method is insufficient, and the scene when the SSD is idle for less than 2 seconds cannot be covered; 2) each space release command ranges from 1 to 65536 sectors, while the space release command issued by the system generally ranges more than 1 sector, and since the size of 1 sector is only 512 bytes, for SSD, the data of 1 sector is very "fragmented" data, and SSD will appear very "hard" when processing such data; the testing strength of the testing method is not enough, and whether the SSD has a defect in design (for example, when the releasing space command is over, the system is subjected to blue screen) in an extreme scene (namely, a scene that each releasing space command only releases one sector of space) is difficult to test; therefore, the demand cannot be satisfied.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a behavior testing method and device of an SSD in an idle state, computer equipment and a storage medium.

In order to achieve the purpose, the invention adopts the following technical scheme:
