The invention provides a data integrity detection method of a solid state disk, as shown in fig. 1, the data integrity detection method comprises the following steps:

and S10, writing data into the solid state disk to be tested by the upper computer, and recording the data written into the solid state disk to be tested at a preset position.

In this step, the data may be written in by electrically connecting the solid state disk to be tested with the test equipment (i.e., the upper computer), so as to facilitate data transmission. The test equipment is preferably a computer, a corresponding test fixture can be arranged at the moment, namely the test fixture is provided with a plurality of test cavities for loading the solid state disk to be tested, the test cavities are internally provided with connectors which can be electrically connected with the solid state disk to be tested, and the solid state disk to be tested can be installed in the test cavities in a manner of being directly inserted into the test cavities. Meanwhile, the data written into the solid state disk to be tested can be preset specific data, can also be data stored in the test equipment by random calling, certainly can also be manually input data, and can also record data information written into the solid state disk to be tested and record the data information at a specific position in the process of writing the data into the solid state disk to be tested.

And S20, stopping writing data when the abnormal power failure of the solid state disk to be tested is detected, and adding stop characters to the data written into the solid state disk to be tested finally.

In this step, the power-off mode may be manual power-off or automatic power-off. The stop character may be a specific stop character, or may be data written to the end of the solid state disk to be tested as the stop character. Because there is a process in the power failure, a small amount of content can be written into the solid state disk to be tested after the power failure information is received.

And S30, when detecting that the solid state disk to be tested is electrified again, reading the data in the solid state disk to be tested, and inquiring the data written in the solid state disk to be tested before the power failure according to the stop character.

In this step, the solid state disk to be tested is powered on again, and the power-on operation may be automatic power-on or hand-to-east power-on, so that the data in the solid state disk to be tested can be conveniently read in a manner that the test equipment directly reads the data. Meanwhile, after data is read, the position of the stop character corresponding to the current test needs to be inquired, so that data written into the solid state disk to be tested before the current power failure is obtained. The position mode of the stop character in the data obtained by the query can be obtained by referring to the existing identification searching mode, such as the existing web crawler mode.

In a preferred embodiment, reading data in the solid state disk to be tested, and querying the data written before the power failure of the solid state disk to be tested according to the stop character includes:

acquiring position information of a stop character;

and inquiring data with preset size written in the solid state disk to be tested before the stop character according to the position information of the stop character.

if the written data is complete, carrying out repeated detection on the solid state disk to be detected for a preset number of times;

and if the written data is incomplete, terminating the detection of the solid state disk to be detected.

In this step, after the data comparison work is completed and the judgment result is output, the subsequent corresponding steps can be executed according to the judgment result, if the judgment result of the solid state disk to be tested is normal, the repeated detection of the preset times is continuously carried out on the solid state disk to be tested, namely, the cycle test of the preset times is carried out on the normal solid state disk to be tested, and the specific test times can be carried out according to the actual conditions; if the judgment result of the solid state disk to be tested is abnormal, the test operation is terminated, namely the solid state disk to be tested is a unqualified product

and the solid state disk to be tested is forced to be powered off within the writing time.

In this step, by obtaining the write-in time of each group of write-in data written in the solid state disk to be tested, the solid state disk to be tested can be forcibly powered off at any time node within the write-in time. The power-off time can be randomly selected, for example, a random model is set to randomly select a time node of each power-off, so that the comprehensiveness of detecting the solid state disk to be detected is increased.
