Problems solved by technology

[0004] In the traditional technology, when the SLC Cache is introduced, due to its limited space, it needs to be moved to the TLC area after it is full. This kind of overwriting will cause additional write amplification, which will affect the performance and life of the SSD.

Abstract

The invention relates to a solid state disk write-in method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a solid state disk write-in request, thesolid state disk write-in request comprising a write command; Monitoring and identifying the write command; Judging whether the write command contains a specific sequence or not; When the write command does not contain a specific sequence, writing corresponding data into an SLC Cache; And when the write command contains a specific sequence, forcibly writing corresponding data into a common area. According to the method, the command sequence is dynamically identified at the running moment of the system, and if certain characteristics are met, data are directly written into the TLC; Otherwise, maintaining the existing strategy, and selecting according to the SLC available space. Through the strategy, write amplification caused by SLC-to-TLC moving can be reduced, and then the service life ofthe SSD is prolonged.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a solid state disk writing method, device, computer equipment and storage medium. Background technique [0002] At present, SSD (Solid State Drive) has been widely used in various occasions, and is gradually replacing traditional hard disks due to its excellent performance, power consumption, and environmental adaptability. [0003] With the evolution of NAND technology, from SLC to MLC, and then to TLC, the reliability and performance of particles are declining, and the existing computer application scenarios have extremely high requirements for performance, so the current SSD manufacturers will provide a High-speed areas, such as reserved SLC Cache, have high read and write performance, so they can provide customers with a better user experience. [0004] In the traditional technology, when the SLC Cache is introduced, due to its limited space, it needs to be moved to the TLC...
