HD Tune Pro 4.01 Benchmark - WRITE 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.

In the HD Tune write test, the SanDisk Extreme 240GB SSD has a very low access time of 0.109ms and average write transfer rate of 350.8MB/s, excellent compared to the OCZ Vertex 3 SSD at 312MB/s. The SanDisk Extreme SSD blows the other SSDs out of the water, and indeed every HDD as you'd expect.
