SMRC: An Endurable SSD Cache for Host-Aware Shingled Magnetic Recording Drives

Host-aware shingled magnetic recording (HA-SMR) drives deliver higher disk capacity and expose internal zones to host, but their performance can be severely degraded when subjected to nonsequential writes (NSWs). Using solid state drives (SSDs) as a cache layer to proactively cache NSWs can alleviat...
