Abstract
A storage device that provides in-storage transparent compression and implements a process for processing write requests during an out-of-space state. The process includes: receiving a write request from a host involving a set of logical block addresses (LBAs); determining if each of the LBAs in the write request is an actively used LBAs; and in response to determining that each of the LBAs in the write request are actively used LBAs, allowing the write request to be served; and in response to determining that at least one of the LBAs in the write request is not an actively used LBAs, not allowing the write request to be served and returning an error to the host.
