CD Write and ReWrite Tests - Nero Burning Rom 7.11.10.0 and Drag-to-Disc 5.20:
For this test I randomly generated 650MB and 700MB of files and directories to test the time it takes the drive to write and close a CD. All of the files are between 1MB and 25MB in size and no more than 10 directories deep.
The BDR-2203 has a maximum CD writing speed of 32x. To reach this speed, it uses Z-CLV, or Zone CLV technology. By looking at the screenshot, you can see that the drive starts writing 16x and jumps to 24x at about the 13 minute mark. The BDR-2203 writes at this speed until about the 44 minute mark. When it reaches this point, its writing speed increases to 32x and stays there until the end of the session.
To test the drive's writing times, I wrote our test data to some Taiyo Yuden media rated at 52x. The results are below.

To test the drive's writing quality I used Lite-On IT's KProbe2. Written by Karr Wang, this utility can be used to test the number of C1 and C2 errors on a disc. For these tests I used a Lite-On LTR-52246S (firmware 6S0F) and read the discs at 32x.

The BDR-2203's writing quality was very good. By looking at the KProbe screenshots, you can see that the discs burned by the drive had a low number of C1 errors. More importantly, there were no C2 errors at all.
For the rewriting tests I created 400MB of files on the hard drive and wrote them in DAO mode using Nero. To test the packet writing speeds I copied and pasted the same files off the hard drive onto a CD-RW disc using Drag-to-Disc from Roxio. Verbatim's 24x Ultra Speed CD-RW media was used for these tests.
The BDR-2203 also uses Z-CLV, or Zone CLV, when rewriting at 24x. The drive starts rewriting at about 16x and then jumps to its maximum speed at the 14 minute mark.

Pioneer's new drive didn't do as well as some of the other drives in our rewriting tests. Due to its Z-CLV writing method, the BDR-2203 took 2:36 to write 400MB with Nero and 2:43 to do the same with Drag-to-Disc.

The BDR-2203 also erases at 24x. At this speed, it took the drive 18 seconds to do a quick erase and 3:41 to fully erase the disc.
