1. A method executed by one or more processors, comprising;
retrieving a data unit from each zoned namespace solid-state drive (ZNS SSD) of a ZNS SSD set of a storage system; and
simultaneously determining for a current cycle, a horizontal parity and a vertical parity, the horizontal parity determined using a data unit stored across each ZNS SSD and the vertical parity determined from the data unit of each ZNS SSD and a vertical parity for each ZNS SSD determined from a previous cycle.
