Erasure code is a forward error correction technology based on data packets, which is of great significance to improve the quality and reliability of network communication. This paper reduces the recovery time by reducing the amount of data read in the recovery process in the erasure coding array storage system based on erasure coding to improve the reliability of data storage. In the paper, a new single-disk error hybrid recovery algorithm is innovatively designed, which makes the data read amount in the recovery process reach the theoretical lower bound. The experimental results show that the hybrid recovery algorithm has obvious improvement in recovery time and disk access time compared with the traditional algorithm.
