AOpen CRW4850 IDE CD-RW - Page 8

RW Writing Tests

With HS-RW media, the AOpen CRW4850 supports 4X, 10X and 12X CLV re-writing speed. For the burning tests, we burned a full 74mins disc with all the drives. The results are showed in the following chart, for the maximum supported speed of each drive.

The faster re-writer comes from Plextor with 224secs. The drive gets the first place due to its 24X re-writing speed. The CyberDrive CW088D comes second with 308secs, the SONY CRX210E1 third with 401secs and the AOpen CRW4850 last with 408secs.

- 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 packet writing performance for the AOpen drive was good and gets the third place. However, the drive cannot compete 24X and 16X re-writers from Plextor and CyberDrive. At the reading part, the SONY drive gets the first place with 20.45X. The AOpen CRW4850 comes second with 20.27X.
