Claim 17:
18. A data storage device comprising:
a disk comprising a plurality of data tracks;
a head actuated over the disk;
a first semiconductor memory (SM) having a first endurance, wherein the first SM is distinct from the disk;
a second semiconductor memory (SM) a second endurance lower than the first endurance, wherein the second SM is distinct from the disk and the first SM; and
control circuitry configured to:
receive a plurality of write commands from a host, wherein each write command includes write data;
determine a size of write data of the write commands;
store, based upon the determining, at least some of the write data in a write cache; and
generate a command execution order for flushing cached write data to the disk, based on a refresh metric of victim data tracks adjacent to data tracks of the disk to which the cached write data are to be written.
