Apparatus, system, and method for storage space recovery

An apparatus for storage recovery, the apparatus comprising:

• a storage division selection module that selects a first storage division for recovery, the first storage division comprising a portion of solid-state storage in a solid-state storage device;
• and
• a data recovery module that,
• reads valid data from the first storage division in response to selecting the first storage division for recovery;
• and
• stores the valid data in a second storage division of the solid-state storage device by passing the valid data through at least a portion of a write data pipeline for the solid-state storage device without routing the valid data outside of a solid-state storage controller for the solid-state storage device.

A system for storage recovery, the system comprising:

• a solid-state storage device comprising solid-state storage;
• a solid-state storage controller for the solid-state storage device, the solid-state storage controller comprising a write data pipeline for the solid-state storage device;
• a storage division selection module that selects a first storage division for recovery, the first storage division comprising a portion of the solid-state storage in the solid-state storage device;
• and
• a data recovery module that,
• reads valid data from the first storage division in response to selecting the first storage division for recovery;
• and
• stores the valid data in a second storage division of the solid-state storage device by passing the valid data through at least a portion of the write data pipeline for the solid-state storage device without routing the valid data outside of the solid-state storage controller for the solid-state storage device.
