Sony CRX175A CD-RW

3. RW reading tests

RW reading tests

- Nero CD Speed v0.84 Results: (Click to see the graph)

For the RW tests we used the Ricoh's HS-RW media written at 10x speed. As you can see below, Sony has the best reading performance among with Yamaha CRW3200E:

CloneCD Tests

- Procedure

We used CloneCD (v3.1.1.0) and 5 original CDs - Euro 2000 (SafeDisc 1), No One Lives For Ever (SafeDisc 2), Rally Masters (LaserLock 1), Desperados (LaserLock 2) and V-Rally 2 Expert (SecuROM 2) - in order to test the reading time of the TEAC CD-W524E. We also tested the reading performance with backups of the original CDs, since the reading speed varies between original and backup media. For comparison reasons we added the results of the already tested PleXWriter PX-W2410A, Teac CD-W524E and Yamaha CRW3200. The following picture shows the reading/writing capabilities of Sony as the CloneCD reports:

- SafeDisc 1/2 Results

Sony CRX175A had hard times to read the original SafeDisk 1 label. Reading the backup cd was easier and the drive finished the task with a 2097,41 sectors/sec reading performance.

With SafeDisc2 protected CDs, things are slightly better for the original CD test. However SONY CRX175A did not give the best performance...

- LaserLock 1/2 Results

Again, with LaserLock 1 protected CDs, the Sony drive performs differently with the original than with the backup CD. The drive, while it needs 20mins for the original disc, it finishes the backup CD at only 3mins. The overall performance of Sony is good and the drive is placed in the second position for this test.

The LaserLock 2 protected CDs are very hard for all recorders to read. Sony CRX175A did manage to finish the task in 26.5 min for the original CD and has the best performance as shown above.

- SecuROM Results

The Sony CRW175A does support reading of SubChannel from Data/Audio Tracks. The reading performance however is slow and comes in the last place since it needs approximately 20 min to read the original or the backup cd.
