Develop an I/O separation scheme using multi-stream feature of solid state drives, which reduces garbage collection overheads, improves I/O throughput, and extends device lifetime.• Design a stream-aware scheduling policy to work with the I/O separation scheme and improve overall I/O throughput.• Improves performance without require users to change their I/O functions.• Increases I/O throughput by 44% and reduce Write Amplification by 20%.
