Abstract

The invention relates to an SSD mapping table protection mechanism verification method and device, computer equipment and a storage medium. The method comprises the following steps: customizing a specific command 1 and a specific command 2; writing specific data into the SSD; reading the data in the SSD, and verifying the correct writing of the data; sending a specific command 1 to the SSD, setting a mapping table entry for the LPA x, and injecting 1-bit flipping; initiating a read operation on the user data of the LPA x; the SSD performs corresponding table items of an internal access mappingtable LPA x and performs error detection; returning correct user data to the host; and sending a specific command 2 to the SSD, and obtaining a table item count of an error occurring in the mapping table for the first time and a table item count of successful error correction. According to the method, various types of errors can be effectively triggered, the processing capacity of the SSD for different types of errors is verified, the reliability of an SSD scheme is effectively guaranteed, and the correctness of user data is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of improving the protection of solid-state hard disk mapping table, and more specifically refers to a verification method, device, computer equipment and storage medium of SSD mapping table protection mechanism. Background technique [0002] SSD (Solid State Drive) has been widely used in various occasions. At present, in the PC market, it has gradually replaced the traditional HDD, providing users with a better experience in terms of reliability and performance. In addition to NAND (flash memory) key components in SSD are protected by ECC (Error Checking and Correction) / CRC (Cyclic Redundancy Check), as users have higher and higher requirements for data reliability, for SSD Non-NAND data protection also puts forward corresponding requirements; typically, there is a large memory in the SSD, which stores a mapping table to manage the mapping relationship between the logical address accessed by the hos...
