1. A method for writing data to a data storage system, the method comprising:
- receiving a reset command for a sequential write pointer of a first zone of a plurality of active zones defined in the data storage system, the first zone associated with a first pointer;
updating a status of a second zone not within the plurality of active zones to an active status; and
updating a status of the first zone to an inactive status.

Abstract
Systems and methods for reducing operational latency of data storage systems are disclosed. More particularly, a data storage device can perform conditioning operations on inactive zones while the data storage device is idle. When an active zone is the target of a write command, the data storage device can exchange a conditioned inactive zone for the unconditioned target zone. The write operation can be performed immediately on the previously-inactive already-conditioned zone. At a later time, the target zone can be conditioned.
