    • Embodiments of the present invention provide a method for managing an SSD storage device and storing data of the SSD storage device, to resolve problems in the prior art of highly complex data management in an SDD and different service lives of NandFlash physical pages in a NandFlash physical block. In the embodiments of the present invention, lengths of a user data area, primary metadata, and an 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, so as to ensure correctness and integrity of the data in the user data area and the primary metadata. This simplifies data management, reduces complexity of ECC hardware logic. In addition, a same service life of each storage unit is also ensured because of a same ECC code rate.
    • 本发明实施例提供一种管理SSD存储设备并存储SSD存储设备的数据的方法,以解决现有技术中SDD中高度复杂的数据管理以及NandFlash物理中的NandFlash物理页的不同使用寿命中的问题 块。 在本发明的实施例中,SSD存储设备的每个存储单元中的用户数据区域,主要元数据和ECC代码的长度被设置为固定值。 其结果是,存储单元中存储的数据的格式是固定的,并且ECC码也可以确保用户数据区域中的数据与固定码率的主要元数据之间的一致性,以确保数据的正确性和完整性 用户数据区域中的数据和主元数据。 这简化了数据管理,降低了ECC硬件逻辑的复杂性。 另外,由于ECC码率相同,所以每个存储单元的使用寿命也相同。
