The Writing Data CD-R discs: For our data The drive used Write Quality: We will test A written CD-R Why wait any
specifications of the NU DDW-082 state that the drive is able to write CD-R
discs at 40x. Let us find out how the drive really performs in speed and
quality.
writing tests, we simply set up a new compilation of 700Mb using Nero Burning
ROM software. Writing method used is DAO (Disc At Once),
and the disc is set up as a non-multisession disc with ‘finalize disc” enabled.
The screenshot below shows how long it takes to write a disc at the highest
speed. (40x):
3 minutes and 2 seconds to write the disc at 40x. Let us see how this compares
to other drives; the Lite-On LDW-811S used 3 minutes and 6 seconds for the same
writing operation at 40x speed, and the Plextor PX-708A used 2 minutes and 58
seconds at 40x. This puts the drive between the Plextor PX-708A and the Lite-On
LDW-811S ‘“ but after all, it’s just seconds in difference. But let’s concentrate
on writing quality, as that is even more important.
CD-R discs from a total of 11 different CD-R manufacturers. To really measure
the write speed, we used the ‘create data CD” function in Nero CD-Speed. The
discs were written at the maximum speed that the drive supports. For the quality
test, we used K-Probe which is a tool developed by a Lite-On Employee. It runs
under Windows and works with drives made by Lite-On. Also note that different
drives and different reading speeds may affect the results obtained when
scanning the discs. We used a Lite-On LTR-52246S drive with firmware 6S0F and
scanned the discs at 48X speed.
disc will always have some C1 errors; C1 errors are easily corrected by the
drive’s error correction capabilities. The next level of errors is C2, while C2
errors could also be corrected by most drive’s error correction capabilities,
they are not wanted on a good quality disc. A good disc should not contain any
C2 errors, and preferably have an average C1 error amount of below 2.0 average
for the best discs, or at least below 10.0 average for good quality discs. After
C2 errors there are only un-correctable errors that will make a disc unusable.

We have found
these Samsung CD-R discs, manufactured by Plasmon, to be of very low quality.
And as we could see they are not even supported by the NU DDW-082 as it failed
with a write error even before starting to write anything to the disc. Stay away
from these discs.

While TDK is a
well-known brand in larger parts of the world, their own manufactured CD-R discs
may not be so well known, as they are mostly only available in
speed only. Interesting to know: This was the only disc to have over 1.0 C1
errors average.
Summary:
Outstanding! That’s the
word that fits best here; if the drive had supported the last 3 discs at 40x
with good quality it would have been perfect. For write quality on CD-R discs
this is the new king of all tested DVD-Writers ‘“ as long as it gets media it
supports. So it gets a huge plus in our book for CD-R writing quality, but also
a small minus for not supporting all CD-R discs.
But after
all, it’s a DVD-Writer, so head on to next page and read about DVD-Writing
performance and DVD media
