CD Recording Tests

- CD-R Writing Tests

The Optorite DD0401 supports 8x, 16, 24x, 32x, and a maximum of 40x CAV writing speeds. The graph below shows the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The writing speed at the beginning of the disc is 18.23x and increases linearly reaching the maximum of 41.17x at the end. According to CDSpeed, the average writing speed with an 80min disc is 31.18x.

As can be seen from the yellow line on the graph below, the rotation speed stayed relatively constant (CAV).

- Recording Times

For the burning tests we created an 80min data compilation with Nero Burning Rom and recorded the data on a 700MB disc. The Optorite DD0401 finished the task in 3:26 minutes, with the 40x writing speed selected. The performance is acceptable for 40x recording speed.

Below are the best write times of the drive for 8x, 16x, 24x, 32x and 40x speeds.

The drive recorded at the maximum supported speed with most media brands we tested. Below you can see the recording times at 40x:

The best recording times for each drive are illustrated below:

Optorite and Plextor drives are faster due to the 40x writing speed. The Plextor drive gave the lowest recording time since it offers 40x P-CAV as opposed to the 40x CAV of the Optorite drive. The Philips drive follows with 24x maximum recording speed.

- CD-RW Writing Tests

The Optorite drive supports 24x P-CAV maximum rewriting speed, with Ultra Speed rewritable media. The following graph shows the results of the writing process with a 24x US-RW from Mitsubishi Chemicals.

The test started at a speed of 18.34x, accelerating to the maximum writing speed of 24.10x at around the 12 minute mark and continuing on at that speed for the rest of the procedure. The average writing speed is 23.42x.

We used Nero Burning Rom in order to burn a US-RW data disc from Mitsubishi Chemicals. The data compilation size was 650 MB and the duration of the recording process with the Optorite DD0401 was very good 03:48min. The best rewriting times for all the drives are presented in the following graph. Note that the Philips drive supports 10x CD-RW.

- Packet Writing Tests

We used InCD and Mitsubishi Chemicals 24x US-RW media for all Packet Writing tests. The formatted disc had 530mbs of free space. We copied a 403 MB file (403.147 KB) from the Hard Disk (on the same PC as the writer) to the formatted RW media through Windows explorer (drag and drop).
