In order to test the writing quality and readability of the burned media we used two readers with two software applications:

In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we overspeed the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.

The measurements below should be taken not as the absolute criteria of the burning quality, but as an indication level.

4X DVD-R Writing Speed

• BenQ 4X DVD-R @ 4X

• SKC 4X DVD-R @ 4X

• Traxdata 4X DVD-R @ 4X

- Summary

According to Plextools, all 4x media exhibited low PIE/POE rates, without POF errors appearing during reading. According to CDSpeed, all media could be read successfully. Judging from the PI/PIF scans we can say that the DUW1608 offers very good quality at 4x recording speed.
