The present disclosure generally relates to methods of operating storage devices. The storage device comprises a controller and a media unit divided into a plurality of zones. Data associated with one or more first commands is written to a first portion of a first zone. Upon a predetermined amount of time passing, dummy data is written to a second portion of the first zone to fill the first zone to a zone capacity. Upon receiving one or more second commands to write data, a second zone is allocated and opened, and the data associated with the one or more second commands is written to a first portion of the second zone. The data associated with the one or more first commands is then optionally re-written to a second portion of the second zone to fill the second zone to a zone capacity, and the first zone is erased.
