Disk Drive Level Workload Characterization

Alma Riska and Erik Riedel, Seagate Research


In this paper, we present a characterization of disk drive workloads measured in systems representing the enterprise, desktop, and consumer electronics environments. We observe that the common characteristics across all traces are disk drive idleness and workload burstiness. Our analysis shows that the majority of characteristics, including request disk arrival rate, response time, service time, WRITE performance, and request size, are environment dependent. However, characteristics such as READ/WRITE ratio and access pattern are application dependent.
