Systems, methods, and apparatus for data placement in a storage device

A method for data placement in a storage device, the method comprising:

• receiving a write command that includes a namespace identifier;
• associating the namespace identifier with a reclaim group and a reclaim unit handle that indicates a reclaim unit within the reclaim group;
• selecting the reclaim unit indicated by the reclaim unit handle based at least in part on a state of the storage device;
• and
• storing data associated with the write command in the selected reclaim unit.

A non-transitory computer-readable medium storing instructions that, when executed by a controller of a storage device including at least one storage medium, cause the controller to:

• receive a write command that includes a namespace identifier;
• associate the namespace identifier with a reclaim group and a reclaim unit handle that indicates a reclaim unit within the reclaim group;
• select the reclaim unit indicated by the reclaim unit handle based at least in part on a state of the storage device;
• and
• store data associated with the write command in the selected reclaim unit.
