CD Write Performance
To test CD write performance, we created a synthetic audio CD using Neros DAE extraction tool. Then we copied the 74 minute CD to an image file stored on the hard drive. We then burned the entire image in one pass. This allowed us to remove any file overhead and test raw burn rate.
As you can see, the Sony is a better CD burner. Its not in the same class as the latest 52x dedicated CD burners, but its a pretty solid 24x CD-R burner and 10x CD-RW burner. Since all current DVD burners now support packet writing for DVD recordable media, we tested packet writing performance on "native" DVD rewritable discs.
