A reconstruction method and device for a redundant array of independent disks. The method comprises: copying data in a fault disk into a redundant array of independent disks (RAID) to a standby disk in the RAID; and writing degraded data into the standby disk, the degraded data comprising data which needs to be written into the fault disk after the RAID is degraded. The data acquisition rate can be effectively improved, thereby improving the data reconstruction efficiency. In the process of data reconstruction, avoiding reading all the data of other member disks except the fault disk can reduce the I / O pressure of other member disks, so that the influence on normal I / O service is reduced, and thus the overhead of a RAID group system is reduced.
