Hello! This program is a wrapper for a dd command in linux. To build this program, run qmake from a console or add the sources to the project and make "build all" option in your IDE. The program is Linux-only, it won't compile on Windows, because it uses Linux-specific libraries and commands. In current version there you can't change the block sizes and their count, but I'll fix it later. Now it writes about 4 gigs of data to your flash drive and works pretty fair. If you have found any bugs, write me to the: https://vk.com/id371871098 or [email protected] NOTE: THE PROGRAM REQUIRES ROOT RIGHTS. TO RUN IT, RUN: cd /path/to/your/directory sudo ./usbspeedtest (in the Release folder)
