Abstract
Variable Capacity Zone Namespace (ZNS) Flash Storage Data Path. In one example, a data storage device including an electronic processor that, when executing a variable capacity scheme, is configured to determine whether a special indication regarding a particular zone in a ZNS is received, delay an association of a final flash block with the particular zone, receive and stage host data for the particular zone in a staging area, receive a zone close request, compact the host data with other host data for storage in other zones into second host data, and move the second host data to the final flash block that is associated with the particular zone and the other zones. The compaction of the host data with the other host data into the second host data reduces or eliminates padding in the final flash block, and consequently, reduces overhead in the data storage device.
