The CERN Disk Benchmark Tool benchmarks Linux block devices and filesystems by measuring sustained large-block write speed and in-place file rewrite performance at a chosen mount point. It supports parallel I/O and captures device statistics with iostat. The tool generates throughput-versus-usage plots and produces a self-contained PDF report, including configuration metadata for reproducible analysis.
