Abstract
A storage device is disclosed. The storage device may include storage for data. A host interface logic may receive a dataset and a logical address from a host. A stream assignment logic may assign a stream identifier (ID) to a compressed dataset based on a compression characteristic of the compressed dataset. The stream ID may be one of at least two stream IDs; the compressed dataset may be determined based on the dataset. A logical-to-physical translation layer may map the logical address to a physical address in the storage. A controller may store the compressed dataset at the physical address using the stream ID.
