Abstract:
The embodiments of the present application relate to the field of storage device application. Disclosed are a data compression method and a flash memory device, wherein the data compression method is applied to a flash memory device, and the flash memory device comprises a flash memory medium. The data compression method comprises: reading at least two pieces of cold data in a flash memory medium; compressing the at least two pieces of cold data in the flash memory medium, so as to obtain at least two pieces of compressed data; splicing the at least two pieces of compressed data, so as to generate at least one write unit; and writing each write unit into the flash memory medium. By means of acquiring cold data and compressing the cold data without compressing hot data, it is not necessary to decompress the hot data when same is subsequently read, such that the IO performance of the hot data is not affected, thereby improving the overall read IO performance of a flash memory device.
