Claim 7:
8. A method comprising:
determining, with a data storage controller, whether a special indication is received from a host regarding a particular zone in a Zone Namespace (ZNS);
delaying, with the data storage controller, an association of a final flash block for the particular zone in response to determining that the special indication is received from the host regarding the particular zone in the ZNS;
receiving, with the data storage controller, host data from the host for storage in the particular zone;
staging, with the data storage controller, the host data in a staging area in response to receiving the host data from the host;
receiving, with the data storage controller, a zone close request regarding the particular zone from the host; and
performing, with the data storage controller, a folding algorithm, the folding algorithm includes
compacting the host data for storage in the particular zone with other host data for storage in other zones into second host data, and
moving the second host data from the staging area to the final flash block that is associated with the particular zone and the other zones.
