CDR Tests

We tested the drive with latest version of Nero/CloneCD. Panasonic LF-D521 supports the 12x CLV maximum writing speed. The drive is also able to write at 8x and 4x, as Nero InfoTool reports:

For all the recording tests, we burned 803MB of data.

One disc was burned with PadusDJ and the other with CloneCD (Amplify Weak Sectors On). The results are posted in the table below:
