Abstract
Description
Technical Field
[0001] This invention relates to the field of solid-state drive (SSD) testing technology, and in particular to a testing method, apparatus, computer equipment, and storage medium for the power-loss protection function of a solid-state drive. Background Technology
[0002] Currently, with the development of technology and the advent of the big data era, data storage has become increasingly important. Therefore, the power-loss protection function of solid-state drives (SSDs) has become particularly crucial, but robustness testing of this function remains lacking.
[0003] Currently, testing power-loss protection functions in an operating system (Windows / Linux) environment is inefficient. The testing process requires manual operation: starting the system, waiting for it to boot, pressing the power button until shutdown, and then restarting to check for system corruption and file loss. The test results can only check the integrity of operating system-related files (whether the system can boot normally), but cannot check the integrity of user data. The testing process cannot be automated, and using relays for timed power-offs cannot effectively preserve failure scenarios in a timely manner, nor can it intelligently determine success or failure.
[0004] Currently, traditional SSD power-loss protection functions generally employ two methods for detection: Method 1 involves manually entering the operating system and pressing the power button for an extended period to artificially induce an abnormal power outage, then restarting to confirm system functionality. Method 2 uses a relay, connecting a wire from the laptop's power button to a relay to simulate manual pressing and automate the process. However, Method 1 has a long testing cycle, requiring manual waiting for the system to boot, and can only observe whether the system can be accessed to determine if critical system startup files are corrupted, but cannot check the integrity of user data areas. Method 2 can automate the power-on and shutdown process, but anomalies during unattended operation may be masked by repeated relay pressing, making it impossible to accurately intercept failures. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0042] Currently, testing power-down protection functions in operating system (Windows / Linux) environments is inefficient. The testing process requires manual operation: starting the system, waiting for it to boot, pressing the power button until shutdown, and then restarting to check for system corruption and file loss. Test results can only verify the integrity of operating system-related files (whether the system can boot normally), but cannot check the integrity of user data. The testing process cannot be automated, and using relay-based timed power-downs cannot effectively preserve failure scenarios or intelligently determine success or failure. Due to these reasons, current power-down protection function testing generally has a limited sample size. Furthermore, given the increasing variety of customized production models, it cannot cover power-down protection function testing under different signal, noise, and timing scenarios on different platforms. Robustness testing of power-down protection functions remains a gap (i.e., it cannot test the actual effectiveness of power-down protection functions in complex scenarios).
[0043] Based on relevant specifications, when the power-loss protection function is enabled, after the relevant mechanism triggers this function, the SSD must stop executing any commands issued by the host and begin migrating data from its volatile storage device to non-volatile storage device, and can record the number of successful migrations. When the triggering mechanism is canceled, the SSD needs to be able to communicate normally with the host to store data.
[0044] Based on this, this patent invention provides a method that uses Ulink's DriveMaster software to write test scripts to enable and disable the power-loss protection function, simulates the raising and lowering of relevant signals and controls the signal duration within a certain range (simulating signal latency caused by different platforms due to signal compatibility, noise processing, etc.), and performs full disk read and write on the SSD after various power-loss resets when the signal is enabled low to verify the actual effectiveness of the function.
[0045] In one embodiment, such as Figure 1 As shown, a test method for the power-loss protection function of a solid-state drive is provided, the method including:
[0046] Step 102: Obtain the test request for the solid-state drive's power-loss protection function;
[0047] Step 104: Write a test script using DriveMaster software based on the test request;
[0048] Step 106: Run the test script to control the power failure protection function to be turned on and off, and write specific data to the entire solid-state drive;
[0049] Step 108: Activate the power failure protection function by simulating the pulling down of relevant signals and controlling the duration of the signals within a certain range;
[0050] Step 110: Control an abnormal power outage using a test script, and check the data format within the solid-state drive after power is restored.
[0051] In this embodiment, a test method for the power-loss protection function of a solid-state drive is provided. The test method uses DriveMaster software from Ulink to write test scripts to enable and disable the power-loss protection function. It simulates the raising and lowering of relevant signals and controls the duration of the signals within a certain range (simulating signal latency caused by different platforms due to signal compatibility, noise processing, etc.). At the same time, under the condition of enabling the signal by pulling it low, it performs a full read and write operation on the SSD after various power-loss resets to verify the actual effectiveness of the function.
[0052] In one embodiment, the step of controlling an abnormal power outage through a test script and checking the form of the data in the solid-state drive after power is restored also includes: comparing the form of the internal data after power is restored with the form of the data previously written to the entire disk to see if there is any difference.
