Abstract
A storage device and method enable processing of un-map commands. In one aspect, the method includes (1) determining whether a size of an un-map command satisfies (e.g., is greater than or equal to) a size threshold, (2) if the size of the un-map command satisfies the size threshold, performing one or more operations of a first un-map process, wherein the first un-map process forgoes (does not include) saving a mapping table to non-volatile memory of a storage device, and (3) if the size of the un-map command does not satisfy the size threshold, performing one or more operations of a second un-map process, wherein the second un-map process forgoes (does not include) saving the mapping table to non-volatile memory of the storage device and forgoes (does not include) flushing a write cache to non-volatile memory of the storage device.
