Abstract
Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, determine an intermediate parity value based on a first parity calculation by sending a uni-directional command to the persistent storage media. The logic is further configured to store, in the controller memory, the intermediate parity value, and determine a final parity value based on the intermediate parity value and a second parity calculation.
