A solid state disk and a data moving method are disclosed. The SSD includes a storage medium and a control chip, where storage space of the storage medium is divided into at least two blocks for storing data, and the control chip includes: a service processing module sends a moving command to a moving module; and the moving module receives the moving command; read valid data from the source block according to the moving command, and perform ECC checking on the valid data; and write checked data into a blank page of the destination block. The SSD can control movement of data from a source block to a blank page of a destination block; compared with a data moving process in which read and write are separated, a path that data moving passes through is simple and reduce impact of the data moving process on performance of the SSD.
