Bonnie++ is a free software file system benchmarking tool for Unix-like operating systems, developed by Russell Coker. Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance.
Features Bonnie++ allows you to benchmark how your file systems perform with respect to data read and write speed, the number of seeks that can be performed per second, and the number of file metadata operations that can be performed per second.Tony.

Sample output
The final CSV output includes the information related to data read and write speed, number of seeks that can be performed per second, and number of file metadata operations that can be performed per second and the CPU usage statistics for the below given tests: Create files in sequential order Stat files in sequential order Delete files in sequential order Create files in random order Stat files in random order Delete files in random order Roch Bourbonnais.
