DYNAMIC STORAGE DEVICE PROVISIONING

摘要

A method or system for allocating the storage space of a storage medium into a permanently allocated media cache storage region, a dynamically mapped media cache storage region, and statically mapped storage region. In one implementation, the dynamically mapped media cache storage region is used for performance and/or reliability enhancing functions.

1. A storage device comprising:
a non-volatile storage medium on a storage disc; and a processor configured to:
allocate storage space of the non-volatile storage medium into (i) a permanently allocated media cache storage region; (ii) a dynamically mapped media cache storage region; and (iii) statically mapped storage region, andchange a performance-enhancing function based on a ratio of size of a mapped section of the dynamically allocated media cache storage region to size of an unmapped section of the dynamically allocated media cache storage region.
