The embodiment of the invention discloses a method, a device, a device and a computer-readable storage medium for storing key information in a solid-state disk. Wherein, the method includes setting the key information memory of the solid-state disk in the memory of the solid-state disk in advance, setting the key information storage area in the NAND, and setting the key information memory of the host in the host; The address space mapping method is mapped to the host memory address space to generate. The host system writes the key information of the preset application into the key information memory of the host, and the key information memory of the solid state disk stores the written key information; when the host is running normally, when the amount of data stored in the key information memory of the solid state disk is not less than Set the capacity threshold, store the data in the key information memory of the solid state disk to the key information storage area, and clear the key information memory of the solid state disk. The application can store key information in time and improve the storage efficiency of key information.
Description
Technical field [0001] Embodiments of the present invention relates to the field of solid-state disk storage technology, in particular to a solid-state disk storage key information methods, devices, devices and computer-readable storage media. Background [0002] SSD is a new type of storage device based on Nand Flash storage media, and its control protocol adopts the NVMe (Non-volatile Memory Express, Non-Volatile Memory Host Controller Interface Specification) standard, which has the significant advantages of high performance and low power consumption. As a block device, SSDs are accessed in blocks, and each block corresponds to a logical block address, which is different from the traditional memory access method. [0003] When running critical applications, SSDs generate a small but very important amount of critical information that needs to be persisted inside the SSD. Due to the block device characteristics of SSDs, the reading and writing of key information must be carried...
