The TEAC DV-W512G supports 48X CD-R and 24X US-RW recording speeds.

• CD-R Format

The drive supports 8X, 16X (CLV), 24X, 32X, 40X (P-CAV) and 48X (CAV) writing speeds. Below are the recording speeds as detected by Nero Burning Rom.

It's quite possible that due to the Generic Smart Control system, the maximum burning speed was reduced down to 32X or even 24X. The user can disable this and obtain the maximum writing speed through Nero Burning Rom->Choose Recorder->Options->Un-tick Generic Write Control.

According to Nero CDSpeed, the drive reached the maximum 48X speed. The test started at 21.56X and finished at 48.70X having an average speed of 36.89X. Click on the image below to see the whole graph.

• CD-R Recording Times

For the burning tests we created an 80min data compilation through Nero Burning Rom, recording the data on a 700MB disc. The TEAC DV-W512G finished the task in 2:40 minutes, for the maximum 48X writing speed.

The writing performance varies according to the inserted media. The Generic write control system will lower the writing speed if the media ID code is not found in the drive's firmware. Below is a chart demonstrating all recording times with various media.

The best performance came with SKC media at 2:40mins, while the highest with Verbatim at 3:21mins.

Overburning writing	Up to 99min
CD text reading/writing	Yes

• CD-RW Format

The TEAC DV-W512G supports the 16X CLV & 24X Z-CLV rewriting speeds with Ultra Speed Rewritable Media (US-RW).

Below you can see the Nero CD-DVD Speed writing simulation test with blank 24X US-RW media from Mitsubishi Chemicals.

The drive starts the writing task at 16.02X and increases up to the maximum 24X at the 14:00 min address mark on the disc. According to CDSpeed, the average writing speed is 22.52X.

We also used Nero Burning Rom in order to burn a data disc with 24X US-RW media from MCC. The data compilation we burned had a size of 651 MB and the duration of the recording process was 3:59 minutes.

Mount Rainier isn't supported by the drive.
