Reading performance:
For these tests we will use Nero CD-DVD Speed to read various CD and DVD's, including audio discs and DVD-media.
Pressed discs:
For this test we used a pressed CD-ROM disc containing Creative Blaster Audigy install CD that is close to 74 minutes long. Below you will see the produced result:
CD-Recordable Discs:
For this test we made a copy of the original Creative Blaster Audigy install CD. The disc we used was a Verbatim 48X certified CD-R disc manufactured by Mitsubishi Chemicals Corporation.
CD-Rewritable discs:
Again, we made a copy of the original Creative Blaster Audigy install CD; this time we used a Verbatim Ultra Speed (24X) CD-RW disc made by Mitsubishi Chemicals Corporation.
The drive is locked at approximately 32x while reading CD-RWs
Audio CD:
We used Nero CD-DVD Speed to measure the transfer rate. The audio disc we used is slightly larger than the disc used for the other tests, to be exact it's about 78 minutes long (77:43:45).
99 minutes CD:
We used Nero CD-DVD Speed to measure the transfer rate. The 99 min disc we used is slightly larger than the disc used for the other tests, to be exact it's about 99 minutes and 57 seconds long.
DVD reading performance:
Again, we will use Nero CD-DVD Speed to measure the reading performance, this time for various types of DVD discs. The drive should read pressed single layer DVD-discs at 16X.
DVD '� DVD-Video:
For our DVD reading performance tests we are going to start with a single and dual layered DVD video discs. While only 1X speed is required to watch DVD movies, it's useful to be able to read the discs at higher speeds if you're going to extract (rip) the content of the disc to your hard drive.
DVD-Video Single Layer
DVD-Video Double Layer
As we can see, it reads DVD-Video Single layer at 16x and DVD-Video Double layer at 8x.
DVD '� DVD+R/RW:
For this test we used one DVD+R and one DVD+RW with about 4,4Gb of data. Below are the results:

Features
It surely looks like CLV to me ... also the image says the same!
Very concerned about the dip during the 16x burns which results in a jump in jitter ... also overall high jitter, which usually mean poorly tuned writestrats and also lower disc lifetimes. Also - overall quality was shocking with some discs.
Wonder why you used a BenQ to scan? For speed only? I find BenQ tend to be less sensitive on some dyes (RICOHJPNR01 in my experience has less errors on BenQ than LiteOn) and heavily error on some others. Still trusting a LiteOn. Your efforts are appreciated a lot!
