TimeWrite is a tool for displaying the "real" performance of a CD writer. This software can operate with any CD-R or CD-RW media, still the most amazing results are usually obtained using CD-R discs.There are three basic types of tests that can be performed:· Track at Once or "Continuous" writing · Variable packet writing · Fixed packet writing Disc at Once or "DAO" writing isn't materially different in how it is implemented in the writer, at least in a performance sense, and is not offered as a separate choice. You would see the same results as those offered by the Track at Once test.Requirements:
