Patent attributes
Apparatus and method for object storage, such as a solid-state drive (SSD) or array thereof. In some embodiments, data arranged as an object are presented for storage to a non-volatile memory (NVM) of a data storage device. Prior to storage, a configuration of the NVM is adaptively adjusted, such as by adjusting a garbage collection unit (GCU) layout, an error correction code (ECC) scheme, and/or a map metadata format used by the NVM. The object is thereafter stored to the NVM using the adaptively adjusted configuration. A controller of the data storage device generates a predicted remaining storage capacity of the NVM in terms of additional objects that can be stored by the NVM responsive to the adaptively adjusted configuration of the NVM. A non-linear sliding scale may be used such that a greater number of smaller objects or a smaller number of larger objects may be accommodated.
