Abstract: An apparatus may include a storage device that may include at least one storage medium and a controller configured to control the at least one storage medium, wherein the controller may be configured to: receive a write command, wherein the write command may indicate a reclaim unit handle; perform, based on the reclaim unit handle, and based on an operation or condition of the storage device, a selection of a reclaim unit of the at least one storage medium; and store, based on the write command, data to the reclaim unit. The storage medium may include a first reclaim group including the first reclaim unit and a second reclaim group including a second reclaim unit of the at least one storage medium, and the selection of the first reclaim unit may include performing a selection of the first reclaim group.

Abstract: Provided are systems, methods, and apparatuses for controlling write amplification factor in storage devices. The systems, devices, and methods include obtaining access to a storage device with a physical storage capacity, a logical storage capacity being mapped to the physical storage capacity, and an overprovisioning capacity being based on a ratio of the physical storage capacity. The systems, devices, and methods include assigning a first portion of the logical storage capacity to a first reclaim unit handle and a second portion of the logical storage capacity to a second reclaim unit handle, selecting the second reclaim unit handle to manage random write operations based on identifying the random write operations on the storage device, reducing, based on the selecting, the second portion of the logical storage capacity, and assigning, based on the selecting, an amount of the overprovisioning capacity to the second reclaim unit handle.

Abstract: A memory is disclosed. The memory may include a first data structure. The first data structure may include a first field to store a first data relating to a command. The memory may also include a second data structure. The second data structure may include a second field to store a second data relating to the command. A first queue stored in the memory may include the first data structure. A second queue stored in the memory may include the second data structure.

Abstract: A memory is disclosed. The memory may include a first data structure and a second data structure. The first data structure may include a first field to store a first data relating to a command, and a related command field, the related command field to store a value. The second data structure may include a second field to store a second data relating to the command. A queue stored in the memory, may include the first data structure. A storage device may be configured to identify the first data structure and the second data structure (405, 705) as related based at least in part on the value.
