CD Recording Tests

- CD-R Writing Tests

To test the writing speed and writing method of the drive we used a blank 80min CD-R disc from TY and NeroCDSpeed to emulate the writing process.

The above screenshot comes from NeroCDSpeed and shows that the external LiteOn SDW-431S, uses P-CAV writing strategy. The writing process started at 10.01X and finished at 24.05X verifying the manufacturer's specification for 24X writing.

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc.

The graph shows different writing times between the drives, something that was expected since each device supports a different maximum recording speed

According to the above graph, at the 24X maximum writing speed for the LiteOn SDW431-S, the Freecom drive's time was about 2minutes faster, This is due to their different writing strategies.

- CD-RW Writing Tests

To test the writing speed and writing method of the drive we used a blank 74min CD-RW disc from TY and NeroCDSpeed to emulate the writing process.

Below we provide a comparison of the three drives where we used Nero Burning Rom software to burn a 651MB data compilation onto 10X US-RW media from TY.

Both the LiteOn and Pioneer drives support 10X maximum re-writing speed and therefore their burning times were about equal. Freecom was faster with 24X maximum re-writing speed.
