AOpen CRW 4850 IDE CD-RW - Page 4

CloneCD Reading Tests

- Procedure

We used CloneCD and 4 original CDs - Serious Sam 2 (SafeDisc 2), Desperados (LaserLock 2), V-Rally 2 Expert (SecuROM 2) and NBA Jam Extreme (PSX) - in order to test the reading times of the drive. We also tested the reading performance with backups of the original CDs, since the reading speed varies between original and backup media. The following picture shows the drive reading/writing features as CloneCD reports:

- PSX Pressed Media

For this test we used the PSX game 'NBA Jam Extreme' and we ripped the image to the HD with CloneCD. The PX-W4824A is the faster drive with only 72secs. The AOpen CRW4850 gets the third place with 175secs.

- SafeDisc v.2 Results

All drives were slow with SafeDisc 2 discs. The faster drive was the PX-W4824A either with pressed or CD-R media. The AOpen CRW4850 performed very badly with CloneCD since the reading speed was locked at 4X after it extracted the bad sectors. Note that when using other software, like Alcohol 120%, the same task is performed at almost full speed (with the AOpen drive) giving of course a much lower reading time.

- LaserLock v.2 Results

The AOpen CRW4850 performed better with the original LaserLock 2 disc getting the first place, but not with the backup one...

- SecuROM v.2 Results

All drives can read SubChannel data from Data/Audio tracks. The faster drive comes from CyberDrive with 2624.18Kb/s. The AOpen CRW4850 gets the third place with 1998.65Kb/s.
