CD Write Tests
1. CD-DVD Speed - CDR Media
The only specs on this drive that don't compete
with other multi-format DVD writers are the CDR write times. Unlike a
majority of other drives which support 40x writing, this drive will support
CDR writing at 32x.
Another thing to note is that the drive uses the
slower Zone CLV recording method. The Nero write transfer tests shown
above demonstrate this use. This method basically divides the CDR into
three zones in which the speed does increase.
I gathered up a variety of media to test
compatibility and write times. Below is a chart of the results.

The results were actually very good! It
wrote to all media at its maximum write speed of 32x and was able to write
exactly 695MB of data in under 4 minutes to some brands of media. Some
may consider its 32x write speed somewhat of a disappointment, however, my
experience with those drives that do burn at 40x is that they actually won't
write to all discs at that speed. With this drive,
you are at least sure you will be able to write at 32x on just about any disc.
2. CD-DVD Speed - CDRW Media
This drive handled CDRW media exceptionally good
as well. It was able to write to both Ultra Speed 24x discs at its
maximum write speed. Below is a table with the results.

3. Over-burning & 99min CDRs
The Pioneer DVR-108 cannot write to 99min CDRs,
however, I did find it quite odd that I was able to burn one music compilation
CD of 92min without any playback issues. The problem is that this was
the only one I could create. After that first one, I couldn't overburn
anymore. This is the first time I ran into this. It's usually yes
or no, but with this drive, it's a maybe. I
installed the drive on another one of my test systems and couldn't duplicate
the 92min burn. Very odd indeed.
Overall, the results of our CD write tests were
very good. It wrote to all media at its rated speed without any issues.
The only thing in question at the moment is whether or not this drive can
indeed over-burn at least slightly.
