CD Recording Tests

- CD-R Writing Tests

The AOpen drive supports 8x, 12x, 16x, 24x, 32x, 40x, 48x, and the maximum 52x CAV writing speeds. Below you can see the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The drive starts writing the disc at 23.01x and reaches a final writing speed of 52.06x. The average writing speed was 39.38x. This test confirmed the manufacturer's specifications of 52x CD recording.

 

 

 

- Recording Times

For the burning tests we created an 80min data compilation using Nero Burning Rom and recorded the data on a 700MB disc. The Freecom FC-1 finished the writing process in 2:38 minutes with selected writing speed of 52x.

Below you can see the best writing times of the Freecom FC-1 for 8x, 16x, 24x, 32x, 40x, 48x and 52x. In each case, the Buffer underrun protection feature was enabled:

The following graph illustrates the recoding times for various media.

As it can be seen from the graph above, the drive burned at 40x many of the tested discs. In the following table we can see which of the discs recorded at 52x and which did not. Also, some media reported 52x recording, such as Creation, but were actually much slower.

We should mention that on several occasions the following message appeared while recording:

- US-RW Writing Tests

The Freecom FC-1 supports the 32x P-CAV maximum rewriting speed for the US-RW format. Below are the results of the CDSpeed writing simulation test with blank 32x HS-RW media from Mitsubishi Chemicals. CDSpeed reported that the maximum writing speed was 32.25x while the average speed was 28.95x. Once again the manufacturer's specifications are confirmed.

 

 

We also used Nero Burning Rom in order to burn a 32x US-RW data disc from MC. The data compilation burnt had a size of 651 MB and the duration of the recording process was 3:07 minutes. The following graph illustrates the time that each drive needed to burn the specific compilation.

- Packet Writing Tests
InCD

We used InCD and Mitsubishi Chemicals 32x US-RW media for all Packet Writing tests. Quick formatting of the media took 30sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (412.822 KB) from the hard disk (on the same PC as the CD writers) to the formatted RW media via Windows explorer (drag and drop).

According to the specifications, the Freecom FC-1 supports MountRainier packet writing. Just as we did with InCD, here too we used a 32x HS-RW media form Mitsubishi Chemicals.
