To ensure the reliability of data storage is an important issue in the field of information, and to study the algorithm to ensure the reliability of data storage is one of the core technologies and hot issues. Tolerant, fault tolerance, codec performance and many other considerations put forward a lot of algorithms. According to the storage performance and coding method, the current data storage reliability algorithms are classified. The typical algorithms proposed in the world are analyzed, including RS, CRS, EVENODD, STAR, X-Code, WEAVER, HoVer and Tornado algorithms. The working principle of them, and put forward a set of performance evaluation index for performance analysis of related algorithms. Summarized the data storage reliability algorithm has the characteristics and needs further study.
