Abstract: An append-only streams capability may be implemented that allows the host (e.g., the file system) to determine an optimal stream size based on the data to be stored in that stream. The storage device may expose to the host one or more characteristics of the available streams on the device, including but not limited to the maximum number of inactive and active streams on the device, the erase block size, the maximum number of erase blocks that can be written in parallel, and an optimal write size of the data. Using this information, the host may determine which particular stream offered by the device is best suited for the data to be stored.

Abstract: Streaming functionality may be utilized for optimizing the storage of data on a solid state device. In one embodiment, an append-only streaming method may comprise determining a size of one or more related groups of data, determining a size of one or more erase blocks in a file system, requesting from the file system one or more stream identifiers based on the size of the one or more related groups of data and the size of the one or more erase blocks, requesting from a solid state device and using the one or more stream identifiers an optimal writable space on the solid state device, and writing data to the optimal writable space on the solid state device.
