1. A method for operating a conventional HDD in a high-density archival storage mode, the method comprising:
providing an HDD configured to store data on a spinning magnetic disk using a recording head, the HDD having an architecture configured to simultaneously meet pre-defined specifications for an areal density metric, a performance metric, and a reliability metric;
writing data to the spinning magnetic disk at a density that exceeds the pre-defined specification for the areal density metric; and
increasing command completion times to thereby reduce performance below the pre-defined specification for the performance metric and to maintain reliability within the pre-defined specification for the reliability metric.
