An embodiment of an electronic device may include: one or more substrates; and a logic unit coupled to the one or more substrates, the logic unit controlling local access to a persistent storage medium, and responsive to one or more commands to: determine an intermediate parity value based on a first local parity calculation, locally store the intermediate parity value, and store the intermediate parity value based on a second local parity calculation. And determining a final parity value based on the intermediate parity value and a second local parity calculation. Other embodiments are disclosed and claimed. 电子装置的实施例可以包括：一个或多个基底；以及被耦合到所述一个或多个基底的逻辑单元，所述逻辑单元控制对持久性存储介质的本地访问，并且响应于一个或多个命令用于：基于第一本地奇偶校验计算来确定中间奇偶校验值，本地存储所述中间奇偶校验值，以及基于所述中间奇偶校验值和第二本地奇偶校验计算来确定最终奇偶校验值。公开并要求保护其他实施例。
