Abstract
A latency reduction method for read operations of an array of N solid-state storage devices having n solid-state storage devices for data storage and p solid-state storage devices for storing parity data is provided. Utilizing the parity generation engine fault tolerance for a loss of valid data from at least two of the N solid-state storage devices, the integrity of the data is determined when N−1 of the solid-state storage devices have completed executing a read command. If the data is determined to be valid, the missing data of the Nsolid-state storage device is reconstructed and the data transmitted to the requesting processor. By that arrangement the time necessary for the Nsolid-state storage device to complete execution of the read command is saved, thereby improving the performance of the solid-state memory system.
