CyberDrive CW099D IDE CD-RW - Page 8

RW Writing Tests

The CW099D supports the new 24X US-RW (P-CAV) recording technology. With US-RW media, the drive supports a variety of recording speeds starting from 10X (CLV), 12X (CLV), 16X (CLV), 20X and 24X (P-CAV).

With HS-RW media, it supports the 4X, 8X, 12X and the 16X (CLV) writing speeds.

For the burning tests, we burned a full 74mins disc with all the drives. The results are showed in the following chart. We used the maximum supported speed for each drive.

The ASUS and CyberDrive recorders gave exactly the same time results and share the first position. Both drives need 3:39mins to finish the task. The AOpen CRW5224 and SONY CRX-220E1 are slower since they use the CAV technology.

With the rest recording speeds we have:

• 20X -> 4:04mins
• 16X -> 5:02mins
• 12X -> 6:44mins
• 10X -> 7:50mins

- Packet Writing Tests

We used Ahead InCD v3.51.61 for the packet writing tests. The formatted disc had 534 MB of free space. We copied a 403 MB file (403.147 kbs) from a Hard Disk (on the same PC as the writers) to the formatted RW media using Windows Explorer (we dragged and dropped) and we completed the test more than once, to eliminate any possible time measurement faults and user errors.

The CyberDrive CW099D performed very well under the packet writing mode with the US-RW media. The drive finished first in the writing process with a 17.09X average speed, while the ASUS CRW5224 comes second with a 16.84X speed. On the reading part, the AOpen CRW5224 gets the first position, and the CW099D comes second. With HS-RW media, the CW099D has the highest performance since it supports the 16X CLV re-writing speed, while the other three drives only 12X.
