Description
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.
