Reducing error correction latency in a data storage system having lossy storage media

A data storage system, comprising:

• a communication bus;
• a lossy data storage device coupled to the communication bus, wherein the lossy data storage device includes lossy data storage, a buffer, and error detection logic, wherein the lossy data storage device, in a read operation, fetches target data of the read operation that includes at least one error from the lossy data storage into the buffer and transfers the target data including the at least one error from the buffer to the error detection logic and on the communication bus, and wherein the error detection logic, during the transferring of the target data on the communication bus, performs error location processing on the target data, and wherein the error detection logic communicates, on the communication bus, error location information regarding at least one error location in the target data;
• an external controller external to the lossy data storage device and coupled to the communication bus, wherein the external controller includes error repair logic that, responsive to receipt of the error location information and the target data via the communication bus repairs the at least one error in the target data using the error location information, and wherein the external controller thereafter causes the target data as repaired to be transmitted toward a destination.
