This paper proposes a Migration strategy based on Reliability disk and Hotspot data called MRH.MRH uses reliability disk estimation to confirm disk reliability based on SMART technology.It computes the heat degree of data and the utilization of disk at the present time, so we can protect the whole data in one disk or current hotspots data.MRH uses hotspot data prediction to predict the hotspots data based on Zipf-like in the future, so we can also protect predicted new hotspots data.Our experiment shows that reliability disk estimation satisfies actual usage and hotspot data prediction achieves very high prediction rate.
