CD Recording Tests

- CD-R Writing Tests

The Freecom drive supports 16x, 24x, 32x and 40x writing speeds for the CD-R media. Just like with the reading processes the drive used CAV strategy for the writing process.

To simulate the writing process we used the latest version of NeroCDSpeed and a blank 48x media from TY. The test confirmed the manufacturer's specifications for 40x recording which is under CAV. The average speed was at 31.41x.

- Recording Times

To compare the recording times of the three drives, we used NeroBurning Rom. We created an 80min data compilation and recorded it on a 700MB disc.The above graph shows the time that each drive needed to record that compilation at the maximum available writing speed. All drives support the 40x maximum writing speed and use CAV writing strategy, therefore their results are almost identical.

Below is the writing time that each drive needed to complete the same recording project at all available writing speeds. The comparison shows that the Freecom drive was the fastest at all four speeds.

In the following graph you can see the recording times with various media brands.

Also, the Freecom drive proved to have stable performance on the writing times with different media brands.

- CD-RW Writing Tests

The Freecom drive supports 24x P-CAV maximum rewriting speed, with Ultra Speed rewritable media. Below are the results from the CDSpeed writing simulation test with blank 24x US-RW media from Mitsubishi Chemicals.

Accurate process with maximum writing speed of 23.99x, a speed that was reached a little after the first 100mb of the writing process.

We also used Nero Burning Rom software to burn a data disc using 24x US-RW media from Mitsubishi Chemicals again. The data compilation, which we burned, had a size of 651 MB. Same writing strategy and same maximum writing speed resulted in similar burning times from all drives.

- Packet Writing Tests

Using InCD and Mitsubishi Chemicals 24x US-RW media for all Packet Writing tests, quick format took 37sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (412.822 KB) from Hard Disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).
