The invention discloses a data processing method and system based on a solid disk array. The method comprises the steps that a write request is received, and the solid disk array and a log disk are instructed to write data corresponding to the write request, wherein the solid disk array includes N member disks, and a hash table is used for indicating last written data in each member disk recorded in the log disk; in idle time, or when the log disk loses efficacy, or when the remaining space of the log disk is lower than a first threshold value, or when the remaining space of a member disk is lower than a second threshold value, the solid disk array is instructed to update check information corresponding to each logical address according to data on N-1 member disks corresponding to each logical address; when the member disk loses efficacy, the last written data in the member disk which loses efficacy is restored through the hash table, and the data on the corresponding logical address in the member disk which loses efficacy is restored according to the data in the member disks which do not lose efficacy and the check information of the corresponding logical address. Through the adoption of the data processing method and system based on the solid disk array, the pre-read operation required for calculating check blocks is not involved, and the original characteristics of an access load are ensured.
