    It's always best to test with a benchmark suite that closely approximates the real life application, so sustained throughput is an important number for copying large files, while random access time is a good metric for reading lots of small files and database use.  Both are available from HDTune, but a more thorough test is IOZone

    For a rough estimate, 1000 divided by the random access time in millisec will give you the number of I/O's per second.
