Description

SSD hard disk performance test method, system, equipment and medium based on read interference Technical Field The invention belongs to the field of computer storage, and particularly relates to an SSD hard disk performance test method, system, equipment and readable storage medium based on read interference. Background In the field of computer storage, NAND (Not AND, meaning "NAND" refers to a storage mechanism of a computer flash disk, chinese is called flash memory) flash memory becomes a necessary choice for enterprise level AND civil level with the improvement of manufacturing process AND the reduction of manufacturing cost. Particularly, when the network speed is faster and faster, the data volume of network traffic data is more and more huge, and an SSD (Solid STATE DISK ) hard disk based on NAND is currently the only memory capable of meeting the explosive growth of data storage services. However, NAND has many problems such as erasing times, increased flash erasing times, abrasion of an oxide layer isolating floating gate electrons, poor insulation performance, and finally data errors, and data storage problems, namely, data stored in the flash memory disappear as time passes, because electrons in the floating gate come out. And read disturbs, as the name implies, when reading the flash memory, it affects the data, and when the number of times that it is read is excessive, it can cause the data correctness to be affected. Therefore, before the data is substantially affected (the read count of a block reaches the threshold a), the NAND data needs to be moved to a new block, erased again, and then ready for use, i.e., force gc (forced garbage collection). The erasing times and data storage of the NAND are often used as important indexes of an SSD hard disk, the service life of the SSD hard disk is influenced, and the problem of read interference is that the read-write speed of the actual service of the SSD is finally influenced due to the fact that the data is migrated to other storage blocks when the read interference mechanism is triggered during data reading, so that the use experience of SSD products and the robustness of the service of a client are influenced. Conventional implementations typically move data to other data blocks based on the memory block reaching the read threshold quickly, but this process is focused in a short time (storm problem) with significant impact on the front-end performance. In the existing method for testing the SSD hard disk, the influence of the read interference of the SSD hard disk on the read-write speed of the hard disk cannot be reflected, and instructive test data cannot be provided for manufacturing the SSD hard disk. Therefore, a hard disk testing method based on read interference is needed to accurately show the influence of the read interference mechanism of the SSD hard disk on the read and write of the hard disk data, so as to guide SSD developers to formulate a reasonable read interference processing mechanism.

In some embodiments of the present invention, obtaining a read disturb threshold of the SSD hard disk, and setting a read data count value of a data block of data in the SSD hard disk to exceed the read disturb threshold includes: And acquiring the read data count values of all the data blocks of the SSD hard disk, and taking the read data count value of the data block with the lowest read data count value as the read interference threshold of the SSD hard disk. In some embodiments of the present invention, obtaining a read disturb threshold of the SSD hard disk, and setting a read data count value of a data block of data in the SSD hard disk to exceed the read disturb threshold further includes: and acquiring the read data count values of all the data blocks of the SSD hard disk, and setting the read data count values of the data blocks of part or all of the data in the SSD hard disk as the read interference threshold of the SSD hard disk.
