METHOD AND SYSTEM FOR USING WEAR-LEVELING USING A MULTI-GAP PROGRESS FIELD

摘要

A data storage device includes a persistent storage and a processor. The persistent storage stores data. The processor obtains a data access request for the data stored in the persistent storage, obtains a portion of the data from the persistent storage using a global migration progress index, and provides the obtained portion of the data in response to the data access request.
