Abstract:
A Solid State Drive (SSD) is disclosed. The SSD may include storage for data and a host interface logic to receive requests from a host machine. The SSD may also include an SSD controller to manage reading data from and writing data to the storage responsive to the requests. The SSD controller may include a flash translation layer to translate logical addresses to physical addresses, a garbage collection logic to perform garbage collection on an erase block that includes a valid page, a stream logic to manage stream characteristics for the data in the valid page, and a restreamer logic to assign the valid page to a new block based on the stream characteristics.
