HD Tune Pro 4.6 Benchmark - READ Tests	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.

The OCZ Vertex 3 240GB SSD weighs in with an excellent average read transfer rate of 375.1MB/s, placing it just slightly behind the SanDisk Extreme 240GB SSD. Thanks to its MLC NAND flash, the OCZ Vertex 3 nets a nice access time of 0.132ms.

In the results chart below we get a better sense of how the Verex 3 compares against several SSDs and enthusiast HDDs.
