CD Recording Tests

- CD-R Writing Tests

The SONY DRU-530A supports 4x, 8x, 16x, 24x, 32x and 40x CAV writing speeds. Below you can see the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The writing process began at 18.23x and finished at 41.19x reporting an average recording speed of 31.91x. According to this, the manufacturer's specification of 40x recording is confirmed.

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc. The drive's time was 3:13 minutes, with 40x writing speed selected. The performance is good for 40x recording speed. LiteOn was faster with only 2 seconds difference while Optorite needed 13 seconds more to complete the task.

Below are the best writing times For Sony DRU-530A drive at 4x, 8x, 16x, 24x, 32x and 40x with a Taiyo Yuden media.

In the following graph you can see the recording times with various media brands. We selected the maximum speed (40x) for all the recorded discs, although the drive lowered this speed to 24x or even less, with Mam-E and Creation media:

- CD-RW Writing Tests

The SONY DRU-530A 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.

The test once again confirmed the drives specifications for 24x rewriting. The burning procedure started at 18.34x and finished at 24.03x having an average speed of 23.43x.

We also used Nero Burning Rom software to burn a data disc using 24x US-RW media from Mitsubishi Chemicals. The data compilation, which we burned, had a size of 651 MB. The duration of the recording process was 3:44 minutes.

Just for comparison, we provide the rewriting time of the Sony drive against those of the Optorite and LiteOn.

- 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).
