data storage processing method for reducing write amplification and a system thereof

The invention relates to a data storage processing method for reducing write amplification and a system thereof. The processing method comprises the following steps: S1, initializing and synchronizinga specific format and a processing strategy of file information; S2, according to the file suffixes, dividing the files into different types, and matching the different types with corresponding ID numbers; S3,carrying out command and data transmission through a PCIe interface and an NVMe protocol, analyzing corresponding bits in the command, and acquiring a file type ID; S4, querying and obtaining a compression algorithm type corresponding to the ID, and performing data compression; And S5, performing address mapping and other common processing on the compressed file, and writing the compressed file into an NAND memory bank. According to the method, corresponding compression strategies are formulated according to different types of data files to obtain the optimal compression effect, so that the data volume store
