Exploring disk performance benchmarks

In the paper we discuss the problem of evaluating disc performance with benchmarks. In particular, we concentrate on assessing benchmark properties. For this purpose we have developed a benchmark managing platform which allows us to enhance the benchmark execution process with monitoring performance counters. The developed methodology and tool do not need additional benchmark instrumentation and have a negligible impact on its execution. The usefulness of this approach has been illustrated with experimental results covering a representative set of benchmark programs.
