Zone capacity

Zone capacity is the maximum number of logical blocks that may be written within a zone.

Zone size describes the address span. Capacity may be smaller, leaving an unwritable tail; multiply logical-block counts by the formatted data bytes per LBA before comparing byte capacities. Early Finish can strand additional unwritten capacity until reset.
