On Improving the Write Responsiveness for Host-Aware SMR Drives.

This paper presents a Virtual Persistent Cache design to remedy the long latency behavior and to ultimately improve the write responsiveness of the Host-Aware Shingled Magnetic Recording (HA-SMR) drives. Our design keeps the cost-effective model of the existing HA-SMR drives, but at the same time asks the great help from the host system for adaptively providing some computing and management resour...
