Abstract: 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.

Abstract: 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.

Abstract: Techniques are described herein for managing data in a storage array. A system includes a distributing unit to distribute compressible data and uncompressible data across compression-capable drives. The system also includes a vacating unit to vacate an excess chunklet to another drive in the storage array if a new compression factor is less than a default compression factor for the storage array.
