CD Recording Tests

- CD-R Writing Tests

The LiteOn LDW-811s supports 8x, 16x, 24x, 32x and the maximum 40x CAV writing speeds. Below you can see the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

The writing speed at the start of the disc is 18.42x and increases linearly to the end of the disc reaching a maximum of 41.51x. According to CDSpeed, the average writing speed with an 80min disc was 31.42x. The velocity throughout the whole writing process remained quite steady.

- 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 LiteOn drive completed the task in 3:11 minutes, with 40x writing speed selected. The performance is reasonably good for 40x recording speed.

Below are the best writing times at 8x, 16x, 24x, 32x and 40x. In each case, the Seamless Link feature was enabled:

What is good about the above times is that the drive seems to be consistent regardless of disc manufacturer.

- CD-RW Writing Tests

The LiteOn LDW-811s supports 24x P-CAV maximum rewriting speed, with High Speed rewritable media. The drive also writes at 4x CLV with NS CD-RW. Below are the results from the CDSpeed writing simulation test with blank 10x HS-RW media from Ricoh.

The drive starts the writing task at 18.53x and reaches the maximum 24x around the 12:00 min address mark on the disc. According to CDSpeed, the average writing speed was 23.53x.

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

- Packet Writing Tests

Using InCD and Mitsubishi Chemicals 24x US-RW media for all Packet Writing tests, quick format took 32sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (403.147 KB) from Hard Disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).
