A cross platform disk benchmark utility written in Java. Measure a drive's read and write speed by creating and accessing data files at your chosen location. Results shown in an easy-to-understand graph, allowing clear characterization of storage device behavior. Tune a benchmark's number of threads, block sequence/size, sample size. Benchmarks are saved for historical analysis.

朋友推荐就下载试着用了下，最新的0.6.0版本对Windows操作系统很友好，没有什么提示就悄不声儿地安装好了，感觉很靠谱，使用起来也方便，可以通过视窗很直观地观察数据流，应用的运行也不占什么资源。少见这样诚心的免费应用，顶一个！

just upgraded to a Crucial T500 2TB and wanted to test read/write it was very easy to use and had a lot of useful information

Este programa me gusto mucho su interfaz y los datos de testeo son muy veloces, esta muy bien optimizado, especifica cada detalle de tu disco duro, seria bueno si tuviera soporte para español y de ahí en fuera es muy eficiente. Lo recomendaría :)
