Abstract
Provided are a solid-state drive and a wear leveling method. The solid-state drive includes a plurality of zones, a mapping relationship and an SSD controller. The SSD controller is configured to: determine, according to the mapping relationship, an identifier of a first target zone corresponding to an identifier of a to-be-written zone in response to receiving a data write command from a host drive unit, and write the to-be-written data to the first target zone. The data write command carries the identifier of the to-be-written zone determined by the host drive unit and to-be-written data, the mapping relationship includes an identifier of an alternate zone corresponding to an identifier of each of the plurality of zones, and the alternate zone of each zone is a zone, determined from the plurality of zones, with fewest programmed/erased cycles.
