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.
