摘要： In some examples, sectors of a solid-state drive are unmapped to initialize the sectors. The sectors include a data portion and a protection portion. When an unmapped sector is read, the solid-state drive can return a pre-set value for the unmapped sector, where the pre-set value includes a known fixed value to represent the protection portion of the unmapped sector. The storage controller is to recognize the known fixed value returned by the solid-state drive responsive to the read as representing the unmapped sector as being initialized, but not written to.

摘要： Examples disclosed herein relate to unmapping sectors of a solid-state drive to initialize the sectors. The sectors include a data portion and a protection portion. In one example, when an unmapped sector is read, the solid-state drive can return a pre-set value for the sector, where the pre-set value includes a known fixed value to represent the protection portion. In one example, a subset of the sectors is unmapped to initialize the subset. In one example, when read, a storage controller can recognize the known fixed value.

摘要： 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.
