DATA MANAGEMENT FOR A DATA STORAGE DEVICE WITH ZONE RELOCATION |
| 摘要 |
Managing data stored on media of a Data Storage Device (DSD) using zone relocation. At least a portion of the media is logically divided into a plurality of zones and zones are identified with access counts greater than or equal to a threshold. The access count for each of the identified zones indicates a number of times data in the zone has been read or written. Data is relocated from at least one zone of the identified zones to at least one destination zone on the media to reduce a data access time between the identified zones. |

1. A Data Storage Device (DSD), comprising:
at least one media for storing data; and a controller configured to:
logically divide at least a portion of the media into a plurality of zones;identify zones of the plurality of zones with access counts greater than or equal to a threshold, wherein the access count for each of the identified zones indicates a number of times data in the zone has been read or written; andrelocate data from at least one of the identified zones to at least one destination zone on the media to reduce a data access time between the identified zones. |
