Abstract: Various zone forwarding management techniques disclosed herein generally provide efficient methods of data caching, steering, mapping, and migration to reduce write amplification and command latency. In one implementation, a zone-forward storage medium management method includes receiving commands to write data sets to target LBAs included in a consecutive sequence of LBAs, selectively mapping the sequence of LBAs to a plurality of contiguous physical zones, and selectively writing the data sets to the physical zones. Various techniques may be used to migrate valid data of the plurality of physical zones to one physical zone.

Abstract: Implementations disclosed herein provide for increasing storage drive performance by reserving a region of user-writeable storage space on a storage medium for overprovisioning uses, including performance-enhancing functions. Until a capacity condition of the storage drive is satisfied, write operations targeting the reserved region are written to another equal-sized region that does not contain user data.

Abstract translation: 本文公开的实现通过在存储介质上保留用户可写存储空间的区域来提供存储驱动性能来提高存储驱动性能，以用于过度配置的使用，包括性能增强功能。 在满足存储驱动器的容量条件之前，将针对保留区域的写入操作写入不包含用户数据的另一等大小区域。
