Abstract

The present application relates to the technical field of solid-state hard disk control, in particular to a method and device for writing data into a solid-state hard disk, and a computer-readable storage medium, which are used to improve the utilization rate of flash, reduce write amplification and increase service life. The above-mentioned data writing method includes: creating a TLB node resource pool and a head node resource pool in the DDR cache; the TLB node resource pool includes a plurality of TLB node resources, and the head node resource pool includes at least one head node resource, and the number of head node resources is equal to The number of TLBPAGEs; after obtaining the data to be written in any TLB PAGE, apply for TLB node resources for the data to be written from the TLB node resource pool, and write the data to be written into the corresponding TLB node resources; and, from scratch In the node resource pool, apply for the head node resource for any TLB PAGE, and write the address information of the TLB node resource storing the data to be written into the head node resource; when the solid state disk is powered off, the TLB node resource pool and the head node resource pool Write the storage content of each node resource in the flash.

Description

technical field

[0001] The present application relates to the technical field of solid-state hard disk control, in particular, to a method and device for writing data into a solid-state hard disk, and a computer-readable storage medium. Background technique

[0002] Compared with traditional hard disks, that is, hard disk drives (HDD), solid state drives (Solid State Drives, SSD) have been widely used in military applications due to their advantages such as fast read and write speed, low power consumption, anti-vibration, and small size. , vehicle, industrial control, video surveillance, electric power, medical, aviation, etc., navigation equipment and other fields. The lifespan of an SSD using NAND Flash as a storage medium is closely related to the number of write operations.

[0003] NAND Flash is mainly divided into three types according to the storage principle, single-level cell (Single-Level Cell, SLC), multi-level cell (Multi-Level Cell, MLC), triple-level cell (Tri...
