HDD Benchmarks: HD Tune Pro Read / Write

HD Tune Pro 4.01 Hard Drive Benchmark Source: HD TUNE

HD Tune Pro is an extended version of HD Tune which includes many new features such as: write benchmark, secure erasing, AAM setting, folder usage view, disk monitor, command line parameters and file benchmark. The benchmark measures raw performance in a couple different ways to measure a hard drive for Read and Write tests, which are conducted separately. To read the results below consider that highest minimum/maximum/average transfer rates are better, while lower (quicker) access times are best. Lastly, highest burst rates are better.
