CD Write Tests
The
DW1625 is capable of writing to CD-R media at 40x. While not exactly the
fastest writer to this media, the difference in write times between 40x and
48x is very minimal.
1.
CD-DVD Speed - CDR Media
The DW1625 uses the faster CAV method of writing
to CD-R media. In our Nero CD-DVD Speed write tests, writing starts at
just under 18x and hits its maximum 40x write speed at the end of the disc.
The average write time was just over 30x.
In our actual write tests, the BenQ DW1625 wrote
695MB in 3:28 minutes. The disc used for testing was a quality Verbatim
52x CD-R. This is just slightly higher than the speediest drives on the
market. A variety of additional media was tested with the DW1625 in
order to thoroughly test its media compatibility.

CD-R media compatibility was very good, able to
write to all discs at their rated speed. Was even able to write to my
trusty Imation 24x "Music" CDRs at 40x. The fastest write times were
achieved with quality Verbatim media as well as the Imation Music CDRs.
Write Quality
1. CD-DVD Speed - CDRW Media
The P-CAV method of writing is used to write to
this format. However, its maximum 24x write speed is achieved early in
the writing process. This results in some rather speedy writing as shown
below.

The drive was also able to write to both my 24x
rated CDRW discs at 24x. Write times were just slightly over 4 minutes.
3. CD-R Write Quality
With CD media, this is measured by the number of
C1 and C2 errors. All discs will report a certain number of C1 errors, but
what you should be more concerned with is the number of C2 errors reported.
If using Nero's Disc Quality Test, I recommend you perform the test using
either 24x or 32x speeds.
While the number of C1 Errors was much higher
than some other drives I've tested, it reported no C2 errors using a Verbatim
52x disc. Write quality was pretty good.
4. Over-burning and 99min CDR Media
Fortunately, BenQ writers do offer full support
for over-burning. While it was not able to write to my Melody 48X 99min
media at its rated speed, it still was able to write 99mins of data with no
playback related issues.
