A method for managing a solid state disk (SSD) storage device and accessing data of the SSD storage device in order to resolve problems of highly complex data management in an SDD and different service lives of NAND flash physical pages in a NAND flash physical block where, lengths of a user data area, primary metadata, and an error checking and correction (ECC) code in each storage unit of an SSD storage device are set to fixed values. As a result, a format of data stored in the storage unit is fixed, and the ECC code can also ensure consistency between data in the user data area and the primary metadata at a fixed code rate in order to ensure correctness and integrity of the data in the user data area and the primary metadata.
