Problems solved by technology
[0004] The erasing times and data storage of NAND are often used as important indicators of SSD hard disks, which affect the life of SSD hard disks. The read interference problem is caused by triggering the read interference mechanism when reading data, which causes data to migrate to other storage blocks and ultimately affects the actual business of SSDs. The reading and writing speed will affect the user experience of SSD products and the robustness of customers' business
The traditional implementation usually moves the data to other data blocks according to the speed of the storage block reaching the read threshold, but this process, centralized processing in a short period of time (storm problem), will have a significant impact on the performance of the front end
However, in the existing SSD hard disk test methods, it is impossible to reflect the influence of SSD hard disk read interference on the hard disk read and write speed, and it is also impossible to provide a guiding test data for the manufacture of SSD hard disks.

The invention provides an SSD (Solid State Disk) performance test method based on read interference, which comprises the following steps: acquiring a read interference threshold value of an SSD, and setting a read data count value of a data block of data in the SSD to exceed the read interference threshold value; and reading data from the SSD hard disk, and calculating and analyzing the reading speed of the read data. The invention further provides an SSD performance testing system based on read interference, computer equipment and a computer readable storage medium. According to the SSD performance test method and system based on the read interference, the read data count value of the data in the SSD is set as the read interference threshold value of the SSD, and then the read test is carried out to accurately obtain the read-write speed of the SSD under the read interference condition. And accurate SSD hard disk read-write test data is provided for SSD designers.
Description
technical field [0001] The invention belongs to the field of computer storage, and in particular relates to a read interference-based SSD hard disk performance test method, system, equipment and a readable storage medium. Background technique [0002] In the field of computer storage, NAND (Not AND, original meaning: "yes and wrong", refers to the storage mechanism of computer flash disks, called flash memory in Chinese) flash memory has become more and more popular among enterprises with the improvement of manufacturing technology and the decline of production costs. An essential choice for grade and civil grade. Especially at present, the network speed is getting faster and faster, and the data volume of network traffic data is getting larger and larger, and the NAND-based SSD (Solid State Disk, solid state drive) hard disk is currently the only memory that can meet the explosive growth of data storage services. [0003] However, there are many problems in NAND, such as t...
