It seems the Lite-Ons are slipping a bit, but still better than Plextor for DAE.

The Premium didn't do as well as some of the other 52x writers we've taken a look at lately. Even then, its performance was far from being poor. By looking at the screenshot, you can see that the drive considered 70.19% of the CD was considered "damaged". Fortunately, none of the sectors on the disc were unreadable.
You can also get an idea of how well the drive can read scratched and dirty discs by using CD DAE. CD DAE will extract the audio tracks twice and then compare them. From this information we can see what the drive's average speed was and how many errors it generated.
CD DAE Avg. Speed Errors % of Disc
Plextor Premium 23.2x 96766657 12.35%
Samsung SW-252B 9.1x 2522782 0.32%
MSI CR52-A2 0.7x 7536092 0.96%
The Premium's performance was hit and miss here. While it had the highest average speed of the three drives here, the number of errors was considerably higher.

The LTR-52246S didn't do as well as I had expected. The drive not only considered 69.18% of the CD to be "damaged", there were a few sectors on the disc that it could not read at all.

Unfortunately, the LTR-52246S was not able to complete this test. Part way through the 12th track, CD DAE would return an "unrecovered read error".

When I took a look at the LTR-52246S, I was a little disappointed by its performance. The percentage of the disc that was damaged was higher than we would have liked and there were even a few sectors on the disc that the drive could not read at all. Fortunately, the LTR-52327S is much better at reading scratched discs. By looking at the screenshot, you can see that only 57.82% of the CD was detected to be "damaged". Better yet, none of the sectors on the disc were unreadable.

Lite-On's new CD-RW did very well here too. While the LTR-52327S slowed down considerably to read our test disc, the number of errors was very low.

To see how well the LDW-811S can read scratched and dirty discs, I used CD Speed's ScanDisc utility to see how many sectors were damaged or unreadable. This is a very rough, but good way to test the drive's error correcting abilities.

The LDW-811S did better than I expected here. The drive considered only 50.84% of the CD to be "damaged" and none of the sectors on the disc were unreadable.
