This
Taiwanese company has shown in the past that is capable of offering technologically
competent drives at very affordable prices. Although a little late, the company
skipped
the 4x DVD recording speed and followed the "plus" camp with the
new
DX082D
8x DVD+RW writer.
The drive is built upon the Philips DVD+RW reference design, based on the
Nexperia PNX7850 chipset. The basic capabilities include 8x DVD+R, 4x DVD+RW,
32x CD-R and 24x US-RW recording. On the reading side the
speeds
are
40x for
CD-ROM
and
12x for DVD-ROM.
- Features
Seamless
Link allows
a CD-RW/DVD+RW drive to automatically monitor the recording status and prevent
buffer under run from occurring.
Seamless Link allows the CD-RW drive to store the RecEnd address, the point
in the data to which the recording mechanism has progressed, and pause the
recording before a buffer under run occurs. When the buffer is again full,
a Seamless Link-enabled drive locates the RecEnd address and resumes the recording
process. The gap between the stop and restart point is closed, while managing
the recording process precisely and transparently-eliminating under run errors
while maintaining recording accuracy.
Dynamic
Calibration
To ensure optimal writing quality over the entire disc at higher writing
speeds, Cyberdrive implements theWalking OPC algorithm, introduced by Philips.
WOPC directly measures and optimizes the actual writing quality during the
writing
process.
At certain intervals, the writing process will be briefly interrupted, the
writing quality directly evaluated and the writing power adjusted accordingly,
if required. The Cyberdrive DX082D uses a more dynamic implementation
based on the position on the disc and the temperature inside the drive.
In addition, Dynamic Calibration includes a tilt calibration feature.
The best reading and writing quality can be obtained if the angle between the
disc and the laser beam is 90 degrees. However, if the disc is warped, the
laser beam will no longer be correctly positioned which will cause a distortion
of the laser spot which will result in decreased writing quality if it is
not corrected.
The tilt calibration will reposition the Optical Pickup Unit (OPU) to maintain
a 90-degree angle between the laser beam and the disc surface at all times
ensuring an optimal spot shape, even on warped discs. The frequency of the
tilt calibration depends only on the position on the disc according to a non-linear
function. Near the end of the disc the risk for warping is higher so the frequency
of the tilt calibration will increase accordingly. As with WOPC, the writing
process will be briefly interrupted, the tilt measured and the OPU repositioned
if required.
Walking OPC and Tilt Calibration together form the Dynamic Calibration. Although
they act independently of each other, some effort is required to synchronize
the Tilt Calibrations with the disc position dependent component of Walking
OPC.

The drive has an 8MB buffer size. Nero Info Tool confirms that
the CyberDrive supports reading of all the media formats except DVD-RAM.
The drive also supports RAW DAO 96 writing (CD). Mount
Rainier is
not supported.
The CyberDrive DX082D drive, as most of the DVD drives, uses the RPC II region
control and allows the user to change the drive's region 5 times. For our
tests, we set
the
region
code to 2 (Europe).
- The drive
By
taking a closer look at the drive itself we can see on the frond panel
the supported formats with their maximum speeds on the left. In the middle
is placed
the DVD+RW logo while the CD rewriteable logo is on the right. A little lower
and left of centre is the indicator light, which is
green while reading and
blinking
green
while writing. Right above the eject button located on the extreme lower right,
can be found the emergency eject
hole.
On the rear panel is the digital and analogue audio outputs
(SPDIF), the IDE connector
and the power input.
Removing the screws and opening the drive's cover voids the drive's warranty.
For reference reasons, we post the following pictures. The CyberDrive DX082D
is built on the Nexperia (Philips/BenQ) DVD+RW reference design. Click
on the mainboard picture for a higher resolution image:
Here can be seen the main chipset of the drive which is the
Nexperia PNX7850 from Philips, same with the one found in Philips latest DVD
recorder DVDR824P.
The difference here is that Cyberdrive implemented all the capabilities provided
by the PNX7850, offering 32x CD-R and 24x CD-RW writing. (24x/10x for Philips
DVR-DVDR824P)
- Retail package
The
retail package includes the DX082D recorder, an installation guide, four mounting
screws, an audio cable and two blank media ( one DVD+R and one DVD+RW).
As for software there is a complete package from Ahead Nero including Vision
Express 2-SE, InCD 4, Nero Showtime etc.
- Installation
The CyberDrive DX082D was connected to our test PC and was identified
as "CyberDrv DX082D" under
WinXP OS. All tests were done with firmware revision v100B.
In the following pages can be seen the test results and in addition a
comparison with three other DVD burners, the Philips DVR824P DVD+RW, the Optorite
DD0401
and the
Plextor
PX-708A
dual DVD burners.
2. Data CD Reading Tests
CyberDrive DX082D DVD+RW - Page 2
Data CD Reading Tests
- Pressed CD results (Click for
CDSpeed results)
The CyberDrive DX082D finished the test at an average speed of 33.23x,
slightly faster than Philips DVDR824P. Both drives offer 40x CAV reading for
CD-R/ROM. Plextor and Optorite drives were also fast with 32.26x and 30.44x,
respectively.
The seek times for CyberDrive were quite good. The Optorite DD0401 leads
the battle being fastest in all seek times, while
Philips
was the slowest.
- CD-R Media results (Click for
CDSpeed results)
We made a copy of the previous pressed CD in order to check
the drive's capabilities when reading a CD-R. CyberDrive was the fastest once
again. It finished the test at the speed of 33.14x average, followed by Philips
DVDR824P.
The CDR-Media seek times did not differ very much from those
of the Pressed CD with the Optorite drive again being fastest.
- ReWritable Media (Click for
CDSpeed results)
For the reading test
we used 24x Ultra Speed rewritable media from Mitsubishi Chemicals.
The CyberDrive's performance with CD-RW was once again similar to that of
previous media. It managed to read the US-RW at an average speed of 33.08x.
It is worth noting that the reading process started at 19.37x
and reached 43.69x upon completion. Philips has the second highest speeed
while Optorite was the slowest.

The 721Abex test disc is hard to read accurately for most drives. The average
error level is -73.7dB(A) which is an acceptable
level and does not lead to audible problems in the
output
signal, according to EAC author. The peaks were lower than -50dB(A) which
means that the odds of a possible problem occurring are fewer.

The Abex TCD-726 is a much easier disc for drives to read. In this case,
the CyberDrive managed to read the disc without reporting any problems, while
only
one sample
was skipped. The total score for the drive is 83.6 out of 100, which is
a very good score.
- CD-Check Audio Test Disc
The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction
/ Error correction capabilities of a CD player. The disc offers a signal combination
with disc error patterns to rate the drive's abilities to read music and reproduce
it completely. Five tracks on the disc contain a sequence of progressively
difficult tests. These tracks are referred as Check Level-1 through Check Level-5.
The
files are reproduced (played) through a software multimedia player (i.e.
Windows Media Player). Each level is considered as passed, if the tone coming
out
from the speakers is smooth, continuous without interruptions, skipping or
looping. The higher the Check Level passed, the more reliable the sound reproduction
of the tested device.

Page 4
DVD reading tests
- Single Layer PTP DVD-ROM (Click
for CDSpeed results)
The CyberDrive DX082D supports 12x CAV reading speed with single layer DVD-ROM
media. From the diagram above it can be seen that the drive managed
to surpass the manufacturer's stated DVD reading speed of 12x specifications,
as well as being the fastest of the four drives.
The performance of the CyberDrive was very good in this test. In comparison
with the other drives, it has the fastest full seek time, while its random
and
1/3 seek times place it somewhere in the middle.
- Dual Layer PTP DVD-ROM (Click for
CDSpeed results)
The two layers of a PTP DVD-ROM disc are read sequentially with the drive
starts reading from the inner tracks of the disc, which is the beginning of
each layer,
moving towards the outer tracks for each layer.
From the graph above it can be seen that the CyberDrive produced the same
performance as the Philips drive, probably due to the use of the same
chipset. However, Optorite was
the fastest in this test with Plextor second.
Although the CyberDrive wasn't the fastest in the DVD dual layer
speed tests, the same doesn't hold true for the seek time tests for the same
media. According
to the graph above, the CyberDrive had the best times in all modes. Especially
in the full seek times, where it was faster than the second placed drive by
11ms.
- Dual Layer OTP DVD-ROM
The
first layer of an OTP dual layer DVD-ROM is read exactly the same way as the
first layer of the PTP disc tested previously. The difference here is the
reading strategy
of the second layer of the disc. The beginning of the second layer is located
in the outer tracks of the disc, so that the drive starts reading from the
outer tracks toward the inner tracks.
In the following screen shot from Nero CDspeed, it can be seen that the drive
performed smoothly over the entire surface. It started
reading at 3.15x and finished at 7.61x
having an average speed of 5.67x.
- DVD Ripping Tests
We measured the DVD-Video ripping speed of the CyberDrive DX082D using the
latest version of DVD Decrypter software. The DVD Video title was the "Matrix" pressed
DVD (single layer, 4.38GB).
The CyberDrive ripped the
DVD movie files to the hard disk
at 7489 KB/s (5.4x) average.
It is not the best time but is still good. Philips had the fastest performance
and Plextor the slowest.
It should be mentioned that although the Plextor PX-708A supports
2x DVD Video ripping by default, pressing the eject button for 3 seconds
(no
disc
inserted)
will
enable
DVD
ripping at
higher
speeds. In this case, the average ripping speed for the same
movie reached the 8,957KB/sec (6.5X).
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed results with the following media:
From the above graph, we can easily conclude that all drives exhibited similar
performance since the differences in maximums does not exceed more than
0.2x. CyberDrive had the second best reading speed after Optorite. In this
typical
comparison, Philips was third and Plextor fourth but once again we mention
that the differences was negligible.
5. DVD Error Correction Tests
CyberDrive
DX082D DVD+RW -
Page 5
DVD Error Correction
Tests
In the following tests the DVD reading capabilities of the Cyberdrive
DX082D drive
with scratched / defective DVD media are examined.
For these tests we used CDVD Benchmark and Nero CDSpeed . The reference test
media
came
from
ALMEDIO.
- Single Layer media
ABEX TDR-821
This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its
surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.
The following transfer rate output was produced by the CDVD Benchmark v1.21
transfer rate test.
The CyberDrive DX082D read accurately the 821 test disc without reporting
any read errors. The defective area didn't affect the reading ability of the
drive.
As a sidenote, the test finished at a speed of 12,8x under CAV.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM with a 4.7GB capacity.
The data structure of the disc is exactly the same as that of the TDR-821,
with
the difference that instead of scratches on the surface there are defective
areas of dimensions ranging from 0.5 to 1.1 mm. There are also fingerprints
sized
between
65 and
75 micrometers.
Once again the drive bypassed the defective area and gave an accurate
reading without errors. The speed reached at the end of the test was 12,8x
under CAV.
- Dual Layer media
ABEX TDR-841
This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches
of dimensions ranging from 0.4 to 3.0mm, in both layers.
Although the transfer rate graph above is not solid, CyberDrive finished
the test without reporting any errors. Once again the defective area in each
layer was bypassed by the drive.
ABEX TDR-845
This test disc is a single sided, dual layer DVD-ROM disc with a capacity
of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the
TDR-845 includes
defective areas and fingerprints. The dimensions of the defective areas range
from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micro meters.
The CyderDrive finished the test without reporting any reading errors, although
the reading graph is not smooth.
ABEX TDV-541
The
TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity of 8.5GB.The
disc is based on the TDV-540 series which is designed for inspection
and adjustment of DVD-VIDEO players. The disc checks the layer switch operation
from layer 0 to layer 1 and also includes test pictures and test signals for
DVD sound files. The current TDV-541 also checks the error correction
capabilities
of the drive and includes scratches sized from 0.4 to 3.0 mm.
The CyberDrive DX082D read the 541 test disc very easily notwithstanding the
reduction of speed at the beginning of the first layer. The starting speed
was 3.17x,
peaking at 7.62x and having an average speed of 5.72x.
ABEX TDV-545
The
TDV-545 test disc is based on the TDV-540 series. It is a single sided, dual
layer DVD-VIDEO disc with a capacity of 8.5GB. The TDV-545 includes artificial
black
dots on the data surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometer
fingerprints.
As can be seen in the following screen shot from Nero CDspeed, the drive
showed smooth performance and finished the test accurately. It is interesting
to note that the maximum speed
reached was exactly the same as in the previous test with teh 541 test disc in
all modes.
6. Protected Data Disc Tests
CyberDrive

- Reading Tests
The purpose of this test is to create an image of the various protected
titles to hard disk. CloneCD v4.3.1.9 software was used with the appropriate
settings,
according
to
the protection type of the inserted discs. Below are summarized the capabilities
of the CyberDrive DX082D drive, according to CloneCD
software.
The game titles we used for each protection scheme are given in the
table below:

PSX Pressed Media
In this test, the CyberDrive managed the second best time
behind the Plextor drive. The ripping process took 98sec for Cyberdrive and
69 for Plextor. The slowest was the Optorite drive with 180 sec. While the
98 seconds needed by the CyberDrive drive was not the fastest, it is nonetheless
a very good time.
SafeDisc v.2
Once again the CyberDrive DX082D had the second best time. The fastest drive
in our comparison was Plextor which was over three times faster than Cyberdrive.
Philips
follows with 302.99 sectors/sec and last is Optorite with 134.97 sectors/sec.
The average ripping speeds for the drives were 15x, 5.1x, 2x and 0.9x for
Plextor, CyberDrive,
Philips and Optorite respectively.
SecuROM v2
In this test the CyberDrive achieved the lowest transfer rate with 1432.36
sectors/sec while Philips had the fastest rate at 2203.63 sectors/sec.
- Writing Tests
For checking the drive's EFM correction status, two different game
titles were used, with different SafeDisc 2 versions and the latest software
patches installed.
After creating the images of the various titles to the hard disk, we burned
them (maximum speed) with CloneCD v4.3.1.9. Two different discs were created
for
each
title; one with the "Amplify Weak Sectors" feature enabled and one
more
with
the
function disabled.
In the table below can be seen whether the produced backups were working
(game installed / played normally), or not.

despite the use of CloneCD.
7. DAE Tests
CyberDrive
DX082D DVD+RW- Page 7
DAE Tests
- Pressed and CDR AudioCD results
According
to CDSpeed, the average reading speed with this disc was 32.58x, and the reported
seek times were adequate.
We ripped the contents of the same audio disc to the hard disk with CDDAE
software. The drive gave an average ripping speed (burst mode) of 29.4x:
In the same test, Philips had the same speed as the CyberDrive at 29.4x
while the Plextor drive gave an average speed of 29x. The Optorite
drive was the slowest due
to their 32x CAV reading strategy.
The same pressed audio disc was copied onto a CD-R and was read again with
CDspeed. the Philips DVDR824P drive gave the highest ripping speed at 29.8x
while teh CyberDrive was marginally slower at 29.7x. The Plextor
drive reached 29.2x, and Optorite's was once again slowest
at 28.1x.
- Advanced DAE Quality
The CyberDrive DX082D achieved a score of 100 (perfect) in the Nero
CD Speed Advanced DAE test. CDSpeed reported that the drive can only read Cd
Text
and
Subchannel Data and not Leadin and Leadout information.
- Support of 90/99mins AudioCDs
The drive managed to rip the audio contents of both 90min and 99min audioCDs.
- Reading/Ripping Protected AudioCDs
For this test procedure two audio discs were used with different
audio protections. The tasks tested are both recognition and
ripping to the hard disk. The software used is Exact Audio Copy.

some mutes
and
skip errors
with the
playback. Only Optorite failed to rip the CDS200 tracks.
8. CD Recording Tests
CyberDrive
DX082D DVD+RW- Page 8
CD Recording Tests
- CD-R Writing Tests
The CyberDrive DX082D
supports 8x, 12x, 16x, 24x and 32x P-CAV writing speeds. Below
can be seen the CDSpeed writing simulation graph when using a 48x CD-R
media from Taiyo Yuden.
Reading
started at 18.67x
at the beginning of the disc and the maximum 32x speed was reached by the
40:00 min address mark on the disc.
According to Nero CDSpeed, the average writing speed for an 80min CD-R was
29.01x. As was mentioned in the first page, Cyberdrive took advantage of the Nexperia chipset
and achieved a 32x P-CAV CD-R recording speed instead of the 24x speed reached
by the Philips DVDR824P drive.
- Recording Times
For this burning test we created an 80min data compilation disc by using
Nero Burning Rom and recorded it at the maximum available speed on a 700MB
disc. The graph
above shows the time required by each drive, at its maximum speed, to write
this test disc.
By looking at this graph it becomes evident that the writing speed varied
considerably among the tested drives. In particular, the Plextor and Optorite
drives recorded at 40x, Philips DVDR824P at 24x while the Cyberdrive DX082x
at 32x.
However, the Optorite drive required around the same time as the CyberDrive
due to Cyberdrive's use of P-CAV
as opposed to Optorite's CAV writing method. The Plextor
drive proved the fastest drive with 178sec, due to its 40x P-CAV
strategy.
Below can be seen the best writing times for the CyberDrive DX082D at 8x,
12x, 16x, 24x and 32x. The disc used was the same for all speeds and came
from Taiyo
Yuden. In each case, the Seamless Link feature was enabled.
The following graph shows the recording
times with different media brands, recorded at the maximum speed of 32x.
Judging from the recording times, the Cyberdrive DX082D reduced the writing
speed during the burning process, with Ritek 48x and SKC 48x media.
- CD-RW Writing Tests
CyberDrive
supports 24x CLV maximum rewriting speed, with Ultra Speed rewritable media.
The
following graph shows results of the writing process with a 24x US-RW from
Mitsubishi Chemicals.
The test started at a speed of 18.67x, accelerating to the
maximum writing speed of 24x at around the 12 minute mark and continuing on
at that speed for the rest of the procedure.
The test finished
at 24.20x.
We used Nero Burning Rom in order to burn a US-RW data disc from Mitsubishi
Chemicals. The data compilation size was 650 MB and the duration
of the recording process with the CyberDrive DX082D was an impressive
03:35min. The
best
rewriting
times for all the drives are presented in the following graph.
As can be seen, the CyberDrive drive was the fastest of all
the drives. The second best time was achieved by the Plextor drive being only
slightly slower. Philips was the slowest in this test with 10x rewriting speed.

same Audio CD project at the maximum speed supported by the CyberDrive DX082D.
In the following graphs can be seen the 3T
Pit & Land Jitter measurements we measured.
- 3T Pit results
According to our measurement the drive performed very well with all the media
tested. The 3T
Pit Jitter values are below the Red Limit (<35ns) in all cases except with
Imation media which had slight lyincreased values. Generally, the drive appears
to be a quality CD-R writer.
Below are the average

- Summary
The measurements with UM Doctor confirmed the very good writing quality
of the drive for all the supported
speeds. The
C1 error
rate
is very
low,
and
only in one circumstance was there a C2 error, specifically with the Taiyo
Yuden media recorded at 32x.
11. DVD Recording Tests

DVD Recording Tests
- Writing Performance
The CyberDrive DX082D supports
DVD+R/RW writing. The maximum supported speeds are 8X and 4x respectively.
We
used an 8x DVD+R disc form Mitsubishi Chemicals in order to check the 8x writing
performance of the drive. The software used was Nero CDSpeed and its "create
disc" function.
The writing procedure started at 6x and after burning approximately 500MB
the speed reached 8x. The process continued as illustrated below. This
behavior is normal according to the manufacturer and it is similar to that
of the Philips DVR824P, not surprising since they both carry the same NEXPERIA
chipset.
As a side note, the test finished at 8.08x confirming the stated specification
speed of 8x for DVD writing. The average speed was 7.6x.
Below
is a screen shot of CDspeed writing test results with a 4x DVD+RW media from
Mitsubishi Chemicals.
Once again the drive confirmed the manufacturers stated specifications for
4x DVD+RW writing. The test showed a solid writing speed of 4x.
- Burning Tests
We burned 4315MB of data on various DVD+R, DVD+RW media.
We used the maximum allowed writing speed for each disc. The best recording
times are illustrated in the following graph. For comparison, we
also include
the
writing
times of
the Philips DVDR824P, Plextor PX-708A and Optorite DD0401 drives.
According to the table above CyberDrive proved the fastest among the
drives when it comes to DVD+R media. It needed 07:48 min
to burn our compilation.
Plextor and Philips burned the same compilation in almost the same time, with
a few seconds delay. Optorite was the slowest with over a minute's difference.
The same cannot be said of DVD+RW media. All
the drives needed around the same time to write the project. The
Plextor
drive was faster
with
only three seconds difference from the next fastest.
The following screenshots are from Nero, after successful burnings with
8x DVD+R and 4x DVD+RW, both from Mitsubishi Chemicals. The amount of data
is
the same for all the tests.

12. PI/PO Error Measurements
CyberDrive DX082D DVD+RW - Page 12
KProbe PI/PO
quality results
The following screen shots present the PI/PO scans for various DVD+R/RW
media, recorded with the CyberDrive DX082D at the maximum alloweable speed.
The software used for the measurements is the KProbe v1.1.26, and the reader
is the LiteOn LDW-401S. The ECC setting was 8. The specific methodology is
very dependent on the drive
used as a reader, and the reliability of the PI/PO provided output is also
not technically confirmed. As a result, we cannot safely come up with absolute
results,
but we are
allowed
to compare
the behavior
of
the
drive
with
various
DVD recordable/rewritable
media. The official DVD specifications demand that PI should be < 280/sec
(PI<<280/sec good quality) and the PO should be zero.
The discs we used come from Mitsubishi Chemicals, Taiyo Yuden, Philips, Hi-Space,
N-Tech and Sentinel. More information about each disc type is available at
the bottom of the page.

We should state that due to the use of the Nexperia chipset we expected the
CyberDrive drive to have displayed approximately the same behavior as the Philips
DVDR824P. This was not
the case however; the Cyberdrive drive pushed the chipset to its limits in
order to offer higher CD-R and
CD-RW writing speeds, while firmware adjustments improved the performance
significantly in areas.
The CyberDrive is the fastest 8x DVD+R recorder we have ever experienced,
offering impressive recording times.
As a point in case, we refer you the excellent 07:48min and
the very good 14:09min times for DVD+R and DVD+RW recording respectively. However,
the
supported
media for 8x DVD+R writing is not very long, as it currently stands for this
speed.
Of course, burning DVD's at high speed is not the only priority, but
a drive should also provide very good writing quality. And in this respect
the CyberDrive does not appear to have
any problems. Far from it, our PI/PO measurements proved the drive is capable
of very good writing quality.
As a CD-R recorder, the CyberDrive was again the fastest, despite its 32x
supported writing speed. Even when competing drives reach
40x writing speeds, nonetheless DX082D
gave the best times. And of course, once again quality should be our guide.
For one more time the drive burned all the media brands we
tested at a high quality, with the measurements for jitter values we took proving
more than satisfactory. What we should note is that the drive did not
record at 32x with all the CD-R
media
we used.
The same thing also holds true with US-RW media. CyberDrive had
the fastest times among the drives.
In reading, the CyberDrive had the highest average
reading speeds, with all type of media, CD and DVD.
The CyberDrive DX082D has good error correction for both CDs and DVD's.
The performance with defective CD media was high, while the 1.5mm defective
area of our
CD-Check Audio Test Disc proved to be a problem for the drive. As for DVD media
the drive read accurately all of our
defective
DVD discs, no matter what the size of the defective area,
without reporting any read errors.
An important issue, however, is that the drive did not manage to make
working backups of all the latest versions of SafeDisc game protection we
tested. SafeDisk versions over v2.51.020 are a problem
for this drive.
On the other hand, the drive managed to rip and playback all of the protected
Audio CDs we tried. Key2Audio
and CDS200 were
not
a problem. The same can be said of 99min Audio CDs.
Although the CyberDrive DX082D is not currently available on the market,
it is expected very soon at a very affordable price, below 150 Euros. Combining
high performance and reliability, the Cyberdrive DX082D is a respectable representative
of the DVD+Rewritable format and rightfully earns our credits.
