Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for reading and writing data, which relate to the computer field, can resolve a problem in the prior art that different algorithms need to be configured for write operations on storage devices of different optimization granularities. The method includes: acquiring first data to be written into a storage device and an address for the first data; acquiring, second data from the address of the storage device; acquiring configuration information; generating, according to the configuration information, a candidate data set; comparing data in the candidate data set with the second data, so as to acquire third data that is in the candidate data set and meets a preset rule; and writing the third data into the storage device according to the address.
