Abstract

A system that includes a storage drive and a controller communicatively coupled to the storage drive. The storage drive includes a first region of storage space that is mapped to a virtual volume and at least a second region of storage space reserved for over-provisioning operations. The controller is to unmap an operable portion of the first region of storage space in response to aging of the storage drive so that the unmapped portion can be used for over-provisioning operations.
