La aplicación es sencilla pero clara y muy funcional. Ofrece una gran cantidad de datos para analizar en cada unidad. Los resultados muestran una gran cantidad de detalles para cada unidad escaneada. Además, funciona bastante rápido. Estoy muy impresionado.

Ontem eu utilizei o jdiskmark pela primeira vez. Simples de utilizar e bem objetivo com com suas funcionalidades. As funções estão bem separadas nas barras de ferramentas e os gráficos provém uma análise precisa e fácil de compreender com a legenda fornecida. Eu apenas não encontrei uma função para selecionar outros discos além do meu primário no qual eu todo meu sistema operacional, porém como o projeto ainda está em beta, vejo isso como uma das funções a serem aplicadas no futuro.

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！
