20. Conclusion
- CD-R Format
The drive supports 8X, 16X, 24X, 32X, 40X and 48X (CAV) writing speeds.
According to Nero CDSpeed, the reported average speed when recording at 40X is 30.38X.
Note here that according to the manufacturer's specifications, the drive supports up to 48X writing speed for CD-R media. In our tests we managed to achieve a maximum of 40X with all inserted media as we will see further on.
- CD-R Recording Times
We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc. The writing performance varies according to the inserted media. Below is a chart depicting all recording times with various media.
As we see in the above graph, fastest burn came with TY media, burned at 40X in 3:15. Several media were burned but unfortunately none of them achieved the max writing speed of 48X.
- Other features

Up to 99min |
CD text reading/writing |

The drive supports CD Overburning up to 99mins.
- CD-RW Format
The drive supports 4X, 10X, 16X (CLV), 24X (Z-CLV) and 32X (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. We also tried writing with 32X RW media and once more, the drive did not confirm the manufacturer's specs, burning at a maximum of 24X (Z-CLV).
The drive, when recording at 24X , reported an average writing speed at 22.38X.
