Disk Benchmarking

IOzone

Option	Documentation
-C	Show bytes transferred by each child in throughput testing. Useful if your operating system has any starvation problems in file I/O or in process management.
-w	Do not unlink temporary files when finished using them.
-c	Include close() in the timing calculations. This is useful only if you suspect that close() is broken in the operating system currently under test. It can be useful for NFS Version 3 testing as well to help identify if the nfs3_commit is working well.
-e	Include flush (fsync,fflush) in the timing calculations
