- Comparison of different writing technologies

The above graph shows the main differences between 24x Z-CLV, 24x P-CAV, 32x Z-CLV and 40x Z-CLV recording technologies. The CyberDrive CW078D is currently the faster recorder and its time differences at 74min CDs are:

- 54secs faster than PleXWriter PX-W2410A
- 49secs faster than Yamaha CRW3200E
- 27secs faster than Mitsumi CR-480ATE

With 80min CDs, the time differences with rest of the recorders are now higher:

- 65secs faster than PleXWriter PX-W2410A
- 56secs faster than Yamaha CRW3200E
- 34secs faster than Mitsumi CR-480ATE

Judging from other 40x Z-CLV recorders, the most of us expected that the LG GCE-8400B using P-CAV to be the faster recorder, especially at the maximum 40x recording speed. Test results showed that a Zone-CLV recorder can be faster than P-CAV with the proper implementation. The time differences from a 24x Zone-CLV are now over 60secs for 80min CDs, which cannot be neglected. However almost all newest recorders require specific media for maximum performance which might disappoint users who wish to use cheap media for their burns.

- Overburning Tests

- CD-Text Results

All tested drives can read/write CD-Text without any problems.

- CloneCD Writing Tests

The CloneCD v4.0.1.3 reports that all drives support the DAO-RAW feature. For the EFM correction (SD2 test) we used 'Serious Sam - The Second Encounter" game titles. We performed both software/hardware EFM corrections test. The only drives that support hardware EFM correction are the TDK CyClone 401248B and LG GCE-8400B, while with the proper software, you could backup all protected discs with the "Amplify Weak Sectors" setting:
