Writing Quality Tests - 3T Jitter Tests

In this set of tests we used various media where we burned the same Audio CD project at all the supported speeds. From the following graphs you can see the 3T Pit & Land Jitter measurements recorded, initially with Taiyo Yuden 48x media, recorded at all the supported speeds and secondly with various media brands, recorded at the maximum allowed speeds.

- 3T Pit results

The values given from the measurements taken reveal very good writing quality at all writing speeds that the BenQ drive supports. At all three speeds, the drive remained well below the Red Book 35nsec level.

The BenQ drive burned at very good quality, all media brands we tested at its maximum speed of 24x. No matter which media brand was used, the drive returned very good results, while only with the Imation disc were the jitter values a little increased (above the 35nsec level), however this should not be a great problem.

Below are the average 3T Pit Jitter values for all tested media.

- 3T Land results

Once again the BenQ drive revealed very good writing quality. The jitter values were quite low.

As with 3T pit, so with the 3T land jitter results, the drive retruned low values, keeping well within the Red Book limit.

Below are the average 3T Land Jitter values for all tested media.

- Summary

The average 3T Pit and Land jitter values are below the 35nsec standard for almost all the media brands. BenQ DW800A displayed high quality writing capabilities.
