CMC 8X DVD+R @ 4X with TEAC DV-W58G

* NU DDW-082 scan @ 8X (CAV) reading speed



* NU DDW-082 scan @ 6X (CAV) reading speed



* NU DDW-082 scan @ 4X (CAV) reading speed



- Some thouhts

The 4X reading speed gave the highest number of samples and accuracy 8.15ECC. It is clear that the PI error rate trend line at the end is there at all reading speeds but the reported values are way too high compared with SA300. The PIF error rate trend line is also present at the end, again with higher values than SA300. Again no POF errors were reported as with a previous test result (check part1).

CMC 8X DVD+R @ 4X with TEAC DV-W58G Jitter Tests

* Reference Scan



* NU DDW-082 scan @ 8X (CAV) reading speed (replaced left axis with right one)



* NU DDW-082 scan @ 6X (CAV) reading speed (replaced left axis with right one)



* NU DDW-082 scan @ 4X (CAV) reading speed (replaced left axis with right one)



- Some thoughts

The Jitter error rate trend line at all three reading speeds can be compared with the SA300. The absolute values doesn't. The SA300 doesn't exceed 13, while the NU drive reported up to 19/17.8 at 6X/4X reading speeds respectively.

Very interesting results!

Thank you for your excellent investigative work again.

If you are in contact with NuTech, can you ask how they calibrate their drives and what kind of sampling frequency/accuracy does the chipset support (for both jitter and causal error rates)?

It looks like the Nexperia chipset based drives could be the next big thing in dvd writing (for both dvd burning quality and reliability of home testing).

regards,
halcyon

Halc thanks for your comments, i will ask those questions soon and hopefully we will have some answers...

BenQ and Philips drives also will be supported soon by CD-DVD Speed, we have lot of work till we can find a reliable drive
