After
the award winning DD0401, Taiwanese
manufacturer Optorite released the DD0405 DVD writer. The new
Optorite drive supports 8x recording for both -R and +R formats and 4x for
rewritable media. With CD-R format, DD0405 supports 40x max writing
speed, just as with its predecesor, the previous DD0401. The drive differs
from the DD0401 only in the
burning speed for +R, which has been boosted to 8x.
- Features

This
dual burner offers 8x DVD+R/-R and 4x DVD+RW/-RW writing and 12x DVD-ROM reading.
The drive is also a 40x/24x/40x CD-RW writer.
Developed by SANYO Electric, a high density recording technology that doubles the recording capacity of conventional CD-R media (700MB).
"Safe-BP" has
achieved enough detection performance at more than 40x speed with the improvement
of the electric circuit for the detection of disarrangement of pickup servo.
When a disarrangement of this servo is detected during high speed recording
conditions, the drive stops the recording immediately and restarts recording
at a lower
recording speed.
Shock-BP
always monitors the condition of the focus servo and tracking servo and stops
the recording when it detects the change in rapid servo condition, then, restarts
the recording at the stop position after the servo condition is recovered.
A
generic name for Flexible Speed and Flexible Strategy. 'FlexSS-BP' technology,
which automatically selects the optimum recording speed for each disc, because
some CDs cannot stand high speed recording with a high recording power.

According to Nero InfoTool, the Optorite DD0405 uses 2MB buffer memory and
supports Raw writing while Mount Rainier and DVD-RAM reading/writing are not
supported.
The Optorite DD0405 uses the RPC II region control, allowing a user to change
the drive's region at most 5 times. For our tests, we set the region
code to 2 (Europe).
- Retail package
The
Optorite ships with an array of Nero applications that include Ahead Nero Express
6, InCD and EasyWrite Reader.
The rest of the bundled software consists of Cyberlink
PowerDVD, Sonic MyDVD and Arcsoft Showbiz.
Besides the software inclusions, the retail package contains the Optorite
drive, mounting screws, an easy installation guide and the audio cable.
- The drive
The front panel of the drive is identical to the DD0401.The usual
DVD/CD and R/RW markings located on the left, centre and right hand sides of
the tray door, with the eject hole on the lower rim and right of centre. The
lower half of the drive's front panel, includes the headphone jack and volume
control situated on the very left, the power/activity led directly below the
eject hole and right of centre, and the next track and stop/eject buttons on
the right. Both buttons are round with the stop/eject being slightly larger.
On the rear panel there are
the analogue audio output, 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 photos. The Optorite DD0405's
mainboard (based on the Sanyo LC897490 chipset) and drive mechanics have been
designed by Optorite, which was also the case with their previous model, the
DD0401. Actually the drive is exactly the same as the previous model, but
the new firmware adds 8x recording for DVD-R. Click on photo of the mainboard
below for a higher resolution image:


- Installation
Our test PC was a 1.8 GHz P4 configured with 512Mb RAM, an
80GB 7200rpm hard drive and Windows XP Professional SP1. The drive was connected
to our
test PC and was identified as "Optorite DVD RW DD0405". All
reading tests were done with firmware v140E. For the recording tests we have
updated the firmware to the latest v150E,
released just a few days before. The new firmware changes the recording mode
with
DVD+R media to the P-CAV (Z-CLV
before), and is expected to offer even faster recording.
The following pages include the test results of the Optorite drive in comparison
to two other dual DVD burners, the Memorex True-8x and the NEC ND-2500A.
2. Data CD Reading Tests
OPTORITE DVD RW DD0405 - Page 2
Data CD Reading Tests
- Pressed CD results (Click for
CDSpeed results)

For this test we used an 80min data pressed CD-ROM disc. When the reading
test ended, NeroCDSpeed reported that the Optorite DD0405 read the disc under
CAV mode.
The above graph shows that all drives returned almost the same speed
with the Memorex being a little faster with all measurements. The Optorite
was the slowest among the three drives but the reported speed meets the manufacturers
specifications
for 40x maximum reading.

Apart from the reading speeds, NeroCDSpeed reported the seek times
for the drives and we present them on the above graph. The Optorite DD0405
proved to
be very
fast. The drive gave back the fastest seek times among the three drives, in
all three modes. The drive finished the full seek test in only 146ms while
the Memorex needed 286ms for the same task.
- CD-R Media results (Click for
CDSpeed results)

On this test we checked the reading performance of the drive with CD-R
media. The disc used is a clone of the previously tested pressed media. On
the transfer rate test of CD-R disc, all three drives had almost the same results
as with the previously tested pressed media. The Optorite DD0405 read the CD-R
under CAV and returned again the slowest reading speed among the drives.
The drive finished the test with an end speed of 40.31x verifying the
40x maximum reading speed for CD-R media.

Once again, with the seek times tests with CD-R media, the Optorite proved
to be very fast, having seek times similar to that with CD-ROM media. The drive
needed 81ms, 97ms
and
147ms for random,1/3 and full seek times respectively.
- ReWritable Media (Click for
CDSpeed results)
For the rewritable reading test we used 24x High Speed rewritable media from
Mitsubishi Chemicals. With the rewritable format, the Optorite supports 40x
reading speed while both Memorex and Nec support 32x and therefore Optorite
finished
the test with the fastest speeds. Once again, the Optorite drive read the disc
under CAV mode and the test finished with an end speed of 40.64x.

This is generally a difficult disc for most drives to read correctly. The
drive was extremely slow when reading the test disc and the scratched areas
were extremely hard to read. After some hours of ripping and analysing,
the drive came up with a poor performance. The situation was the same in the
case of the previous Optorite model, the DD0401. The number of total errors
is on the high side, asa is the maximum error level at -4.8 dB(A).

The results of the Optorite with the 726 Abex test disc are not the best we
have seen but they are at an acceptable level. The software awards the drive
with 80.7 points
out of 100.
- 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
more difficult tests. These tracks are referred to as Check Level-1 through
Check Level-5.
The
tracks are reproduced (played) through different software multimedia players (i.e.
Winamp, PowerDVD, 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 drive.

Although we didn't expect Optorite to perform well on the Audio test Disc
because of its performance with the previous CD error correction tests, on
this test the results were perfect. The drive managed to playback all levels
of
the disc succesfully. There were no audioable clicks,
muted or skipped areas. We should also mention that most drives do not
manage to reach the fifth check level.
Error concealment circuitry works very well in this case.

indicates the drive has problems and offers low performance with scratched
media (TCD-721R). With less seriously defective discs, the drive is very strong.
4. DVD reading tests
OPTORITE DVD

Page 4
DVD reading tests
- Single Layer DVD-ROM (Click
for CDSpeed results)
The graph above shows that Optorite returned the slowest results among the
three drives on the reading test, since it did not reach the manufacturer's
specifications of 12x reading. Optorite's
average
reading
speed
was 8.83x while Memorex was the fastest with 9.46x.
On the seek times test, the Optorite DD0405 returned the best results of
the roundup. In all three modes the drive was fast with reported seek times
105ms, 109ms
and
176ms for Random, 1/3 and Full seek times respectively. The worst result comes
from
Memorex on Full seek, where the drive needed 308ms to finish the test.
- Dual Layer PTP DVD-ROM (Click
for CDSpeed results)
The two layers of a PTP DVD-ROM disc are read sequentially with the drive
starting the read process from the inner tracks on the disc, which is the beginning
of each layer,
and progressing outwards towards to the outer tracks for each layer.
On the previous tested single layer DVD-ROM the Optorite returned the slowest
reading speed among the three drives and therefore we had expected the same
performance on this test. Instead, the drive logged in faster reading
times than
the other two drives on the dual layer DVD-ROM reading test. Once again the
test confirmed the manufacturers specifications for 8x reading speed.
Once again Optorite proved to be very fast on the seek times test with DVD
media. The above graph shows that the Optorite returned the fastest
seek times among the three drives in all three modes.
- 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 we tested previously. The difference here is the
reading strategy
of the second layer on the disc. The beginning of the second layer is located
in the outer part of the disc, so the drive starts reading from the outer tracks
inwards towards the inner tracks of the disc.
The Dual layer OTP DVD-ROM was read under CAV mode. The reading process was
smooth and the seek times were relatively fast. The reported start
speed was 3.55x while the reading speed at the end of the first layer reached
8.51.
- DVD Ripping Tests
We measured the DVD-Video ripping speed of the Optorite DD0405 using the
latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed
DVD-Video.
DVD Decrypter reported that the process ended after 19:17minutes with
maximum read rate 11.946KB/s (8.6x). The above graph shows the average ripping
speed of each drive and we can conclude that the Optorite was by far the fastest
among the three drives with an average ripping speed of 6.8x
- DVD Recordable / Rewritable reading Tests
The chart below shows the Nero CDSpeed average reading speed results with
the following media:


Due to the fact that the Optorite DD0405 supports CAV reading strategy and
8x maximum reading speed for all writable media, the reported reading speed
of all media is nearly equal. From the above two graphs we can see that
the Optorite
was
the fastest with the reading test.
5. DVD Error Correction Tests
OPTORITE DVD
RW DD0405 -
Page 5
DVD Error Correction
Tests
In the following
tests we examined the DVD reading capabilities of the Optorite DD0405 drive
with scratched / defective DVD media. For the tests we used CDVD
Benchmark and Nero CDSpeed. The reference test media
come
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 picture comes from the CDVD Benchmark v1.21 transfer
rate test.
The above screenshot shows that the Optorite drive had some problems with
the 821 test disc. Despite the fact that the test ended without errors, the
drive didn't manage to read it under CAV. However, using the 5x CLV mode the
disc was read accurately.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM of 4.7GB capacity. The
data structure of the disc is exactly the same as that of the TDR-821, with
the difference that there are no scratches on the surface and instead
defective areas ranging in dimensions from 0.5 to 1.1 mm. There
are also fingerprints with height
between
65 and
75 micrometers.
The Optorite DD0405 managed to finish the 825 Abex test fast and accurately.
The reading process started at 5x and under CAV mode finished at about 12x.
- 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, on both layers.
The above screenshot shows that Optorite managed to finish the Abex TDR-841
test disc without errors (red spots). Again the drive behaved as in the case
of the corresponding single layer disc, lowering the reading speed to 5x to
maintain reading accuracy. Also notice the large number of speed changes (large
group of yellow dispersed dots) at the beiginning of the disc, where the drive
first encounters the scratches.
ABEX TDR-845
This disc is a single sided, dual layer DVD-ROM disc with capacity of 8.5GB.
The only difference between the TDR-845 and the TDR-841 is that the first includes
both defective areas and fingerprints. The dimensions of the defective areas
range from 0.5 to 1.1 mm and the fingerprints have height sized from 65
to 75 microns (micrometres).
The above screenshot shows that Optorite managed to read the effected areas
of the first layer without problem while top speed reached was about 9x.
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 correcting
capabilities of the drive and includes scratches sized from 0.4 to 3.0 mm.
The reading process started at 3.56x under CAV mode but when the drive reached
the defective area the speed was decreased from 5.2x to 4.4x. On the other
hand the above graph shows smooth switch operation from layer 0 to layer 1.
The test ended without
producing any error messages.
ABEX TDV-545
The
TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer
Video/S-2 disc with a capacity of 8.5GB. The TDV-545 includes artificial
black dots on the disc's surface, sized from 0.4 to 1.0 mm. It also has 65
- 75 micrometre high fingerprints.
The Optorite DD0405 read the Abex 545 test disc without problems.
Both layers were read smoothly and accurately while the reported seek times
and average
speed were very
good.
6. Protected Disc Tests
OPTORITE DVD RW DD0405 -
Page 6
Protected Disc
Tests
- Reading Tests
To create an image of the various protected titles onto a hard disk, we
used CloneCD v.4.3.1.9 software and the appropriate settings, depending on
the protection type of the inserted discs. Below are summarized the capabilities
of the Optorite drive, according to CloneCD
software. Notice that the drive supports writing of CD+G under RAW DAO:

The game titles we used for each protection scheme are given in the
table below:
Game Title
|
Protection Scheme
|
PSX "NBA
Jam Extreme"
|
Lybcrypt
|
Serious Sam The Second Encounter v1.07
|
SafeDisc v.2.60.052
|

|
SecuROM v.2
|
PSX Pressed Media

SafeDisc v.2

SecuROM v.2

The Optorite DD0405 managed to make images of all tested games. The above
graphs show that the drive was the fastest image making device among the three.
The Optorite DD0405 supports the DAO-RAW writing mode.
For checking the drive's EFM correction status, we used 3 different game titles
with different SafeDisc 2 versions with the latest software patches installed.
After making the images of the various titles to the hard disk, we burned them
(maximum speed) with CloneCD. Two different discs were created for each
title; one with the "Amplify Weak Sectors" enabled and one more with
the
function disabled.
The table below shows the results of the attempted backups and whether
they ran (game installed / played normally), or not.

As we expetced, the DD0405 is not a good backup solution. The drive made
a valid image only with on one game protection scheme. The earlier version
of Safedisc result to a
working
backup
but only when the Amplify Weak Sectors option was enabled. The same game didn't
work when we burned it without the Amplify option enabled. With all other games,
the drive failed to produce a working backup.
7. DAE Tests
OPTORITE DVD
RW DD0405-
Page 7
DAE Tests
- Pressed and CDR AudioCD results
The Optorite DD0401 supports a maximum reading speed of 40x, and reads
audio discs under CAV mode.
Like
all media tested up to this point, the Optorite read the pressed DAE disc under
CAV mode. The average reading speed was 30.53x. The test started at 17.74x
and
finished with an end speed of 40.32x. The seek times are slightly increased
than the reported seek times of data discs but still at very acceptable levels.
To test the ripping capabilities of the Optorite with DAE discs we used
the previous tested disc, making a clone on CD-R media using the
EAC software. We
present the results on the graphs below.
The Memorex True-8x was the fastest among the three drives
on both pressed and CD-R DAE discs while the Optorite came in second.
EAC reported
that the Optorite was slightly faster on the ripping process with the CD-R
audio disc at an average ripping speed of 28.4x while with the pressed DAE
disc the average
speed was 27.7x.
- Advanced DAE Quality


In the Nero CD Speed Advanced DAE test, the Optorite DD0405
returned an average speed of 28.8 x which is the fastest among the three drives.
On the quality score the drive was awarded with a perfect score of 100 while
according to Nero Advanced DAE quality the drive can safely be used for on
the fly copying
up to 16x.
On the advanced features the software reports that the Optorite supports
Leadin,
Leadout, CD Text and subchannel data.
- Support of 90/99mins AudioCDs
The Optorite DD0405 didn't manage to rip all the contents of the 99min Audio
disc. The test disc contains 25 tracks and the ripping process stopped with
timing errors after the extraction of the 20th track at the 83:46:43 minute
mark.
- Reading/Ripping Protected AudioCDs
For the test procedure we used two audio discs with different
audio protection schemes. We tested for both recognition and
ripping to the hard disk. The software used was Exact Audio Copy.
* Pressed Audio disc protected by Sony Key2Audio (Celine
Dion - New Day
Has Come)
* Pressed Audio disc protected by Cactus Data Shield 200 (Natalie

The Key2Audio disc was not a problem for the Optorite. The drive managed to
playback and rip the contents of the protected disc without problems or audible
clicks during the rip. The Cactus protected disc however, presented a
weird behavior. When we launched EAC and tried to rip the disc, the reported
ripping
speed
was 0.1x and timing problems were reported. Alternatively when we chose to
rip all the other tracks except for the first, the process started normally
and finished without any errors.
8. CD Recording Tests
OPTORITE DVD
RW DD0405 - Page

CD Recording Tests
- CD-R Writing Tests
The Optorite DD0405 supports 40 maximum reading speed under CAV writing strategy.
To emulate the writing process we used the latest version of NeroCDSpeed and
a blank CD-R 48x from TY.
NeroCDSpeed
confirmed the 40x maximum writing speed for the Optorite writer. The writing
process started at 18.23x while CAV writing method was used for the process.
The test finished with a 41.16x end speed resulting in an average speed of 31.16x.

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it
on a 700MB disc. The above graph shows that the Optorite was fastest on the
writing test, something that was expected since the Memorex support 24x and
the Nec 32x, while the Optorite
supports 40x maximum writing speed.
Below are the writing times at all avaliable writing speeds for the Optorite.

In the following graph you can see the recording times with
various media brands. All media took about the same time except
for the AM disc needed 234sec, meaning that it was written at about 24x instead
of 40x.

- CD-RW Writing Tests
In order to test the writing process with a rewritable CD-RW
media we used a blank 24x US-RW media from Mitsubishi Chemicals and NeroCDSpeed
The
test confirmed the drives specifications for 24x rewriting. The disc was written
under P-CAV mode, the burning procedure started at 18.34x, finished at 24.01x
having an average speed
of 23.42x.
In order to provide a comparison of the three drives when writing on HS-RW
media, we used Nero Burning Rom software to burn a 651MB data compilation using
24x US-RW media from Mitsubishi Chemicals.
The above graph shows that the Optorite finished the writing process faster
than the other two drives.
- Packet Writing Tests
For the packet writing test we used the InCD packet writing software from
Nero and Mitsubishi Chemicals 24x US-RW media. The test file was a 403 MB file
(412.822 KB) and we used the drag and drop method from Windows Explorer to
write
the file from our hard disk to the RW media.

Writing Quality Tests - 3T Jitter Tests
In order to test the writing quality of the written disc with the Optorite
drive we summarize the
3T
Pit & Land Jitter of the written discs on the following graphs.
- 3T Pit results

The above graph shows that almost all discs exceed the 35ns Red Book limit
with the Pit values.The best quality written disc, with the lowest Pit levels,
is Smartbuy from Prodisc while the highest measurement comes from Am, Plasmon
manufacturer,
which returned unacceptably high jitter at the end.
The average
3T Pit Jitter values for all media brands are illustrated
in the following table.
Three of the five written discs gave back high average Pit Jitter
values. Smartbuy and Benq proved the best quality
written media .
- 3T Land results

The Land Jitter values for the same media, written with the Optorite DD0405
were slightly increased in comparison to the Pit values. In these measurements,
only Smartbuy gave back low Land values but still over the Red Book
limit at the outer area of its surface.
The following average graph confirms the low levels.

On the above graph are summarized the average Land Jitter measurements for
all written media. The average values for all media, except Smartbuy,
are well
over the 35ns RedBook limit.

- Summary
UmDoctor showed that the Optorite provided quality CD-R writing
with TY discs, while the AM and Benq, from Plasmon and Acer respectively gave
back
high C1 errors. In the case of the AM disc, a lot of C2 errors were reported
and the disc was not readable with the Optorite DD0405, as well as all other
drives we tested it with.
11. HD-BURN tests
OPTORITE DVD RW DD0405 - Page 11
HD BURN FUNCTION
HD-BURN
allows writing twice the amount of data than can normally fit on a CD-R disc.
This means that up to 1.4GB of data can be recorded on 700MB CD-R media. The
Optorite DD0405 supports 24x writing speed for the HD-Burn option.
To check the performance of the Optorite DD0405 under HD-Burn we used NeroBurning
Rom that supports the HD-Burn function. The available HD-Burn compilations
are
CD-ROM (ISO, UDF, ISO/UDF, Bootable), HD-BURN -Video or just copy an HD-BURN
disc.
- HD-BURN Writing
We used the HD-Burn ISO compilation of Nero to create a data disc that
contains 1400mb. The writing process finished after 8:10 minutes and Nero
informed us
that the burn process was successful.

- Reading the HD-BURN discs
The
HD-Burn written disc was fully readable with the Optorite drive. Unfortunately
no other device was able to read the specific disc and that was expected since
the HD-Burn function had the same performance on the previous versions of Optorite,
the DD0203 and DD0401.
We
used the Optorite for the reading test and NeroCDSpeed. The disc was read
under CAV mode and the drive reached the maximum reading speed of 80.43x at
the end
of the test confirming the stated 78x speed, as per the manufacturer's specifications.
Note that these speed marks look really high compared to those from 700MB
data discs.
This is because of the increased density of the recorded data under the HD-BURN
mode.

12. DVD Recording Tests
OPTORITE DVD RW DD0405 - Page 12
DVD Recording Tests
- Writing Performance
The Optorite DD0405 supports DVD+R/RW and DVD-R/RW writing. The maximum
available writing speed is 8x and 4x for writable and rewritable formats respectively.
The writing strategy for writable media is the *Z-CLV while both rewritable
media were written under CLV.
8x DVD-R
After
the end of writing simulation, NeroCDSpeed confirmed that the maximum writing
speed for -R media is 8x. The process started at 4.04x and ended with a maximum
writing speed of 8.14x resulting in an average speed of 6.88x. The screenshot
below, shows that the speed increased from 4x to 8x after 1/3 of the total
process.

8x DVD+R
Once
again the manufacturer's specifications for 8x maximum writing speed were confirmed
after the end of the test. The writing process started at 4.03x and ended at
8.06x resulting in 6.88x average speed, a value that is identical to the
previous tested -R media. The screenshot from NeroCDSpeed shows that the drive
had to write about 1.2Gb in order to increase speed from 4x to 8x.

*After upgrading the firmware to v150E, the drive recorded on DVD+R media
using the 8x P-CAVmode. This increased the DVD+R average recording speed to
7.74x (!), at least with some 8x media. In other cases, the drive lowered the
recording speed to 4x by the end of the recording process:
- Mitsubishi Kagaku 8x DVD+R

- Philips 8x DVD+R (Philips C08)


4x DVD+RW
The
maximum supported speed for DVD+RW is 4x. NeroCDSpeed confirms smooth writing
for rewritable media while the speed is slightly increased during the process
from 3.97x to 4.04x. The simulation ended with an average writing speed of
4.04x

4x DVD-RW
We were not able to perform the -RW writing simulation with NeroCDSpeed.
When we launched the program and pressed the start button to begin the process,
the drive was spinning fast and noisy and the process didn't start. However,
the 4x DVD-RW disc was succesfully burned with Nero Burning Rom.
- Burning Tests
The following graphs show the maximum writing speeds for all available DVD
formats for the Optorite drive. For comparison, we also include the writing times
from Memorex True-8x and Nec ND-2500A.
All three drives supports 8x maximum writing speed for the writable media
and 4x for the rewritable.
As can been seen from the graph above, the Optorite was the fastest for
the +R format due to its writing strategy, P-CAV as opposed to Z-CLV. In
the -R format, the Memorex
proved to be the best.
The following screenshots were taken from Nero, after successful burnings.
The recording project is the same
dvd-video compilation for all the tests.

13. KProbe PI/PO quality tests
OPTORITE DVD RW DD0405 - Page 13
KProbe PI/PO
quality results
The following screenshots show the PI/PO scans for the various DVD-/+R
and DVD-/+RW media, recorded with Optorite DD0405 at the maximum permitted
speed.
The software used for the measurements was the KProbe v1.1.26, the ECC was
set to 8 and the reader was LiteOn LDW-811s. The specific methodology is very
dependent on the
drive
used as a reader, while the reliability of the PI/PO provided output is also
not technically confirmed. Hence as a result, we cannot safely come up
with conclusive results,
although we do make a comparison
of the drive's behavior
when using
various
DVD recordable/rewritable
media.
The discs used came from CMC, Verbatim, Maxell, JVC, Mam, Taiyo Yuden, TDK,
and Mitsubishi Chemicals . Further details about each disc type are presented
at the bottom of this page.

All used discs that were certified for 8x writing were successfully written
at 8x. Apart from this, among the used discs the MCC 4x DVD+R
was written at 8x but gave back worst PI/PO measurements. All discs had increased
PIPO
values
at the end of their surface but the results are quite acceptable. In the case
of MAM-e media, CDSpeed and KProbe did not manage to read the disc.

The new Optorite DD0405 has no basic differences from the previously released
DD0401. This means that the new Optorite is a trusted device for DVD and CD
writing tasks but not a good solution as a game protected backup writer.
The retail version of the drive does not include much except from the writer.
We believe that all drives should include in their retail packages some blank
media, something that was not the case with the Optorite.
The new DD0405 was fast on the reading tests of all CD-R media we tested but
what was really a plus for the dual writer were the reported seek times. With
all tested media, the Optorite was the fastest in all seek times among
the drives
used in the comparison.
With the CD error correction tests, the Optorite DD0405 returned
the best results possible with the Audio CD-Check test disc.
The drive managed
to pass
successfully all five levels of the test and that means that users who will
choose the drive will be able to playback old and scratched audio CD-R media.
The other two drives of the roundup, Memorex True-8x and Nec ND-2500A reached
up to 4th and 2nd level respectively.
The Abex CD Error correction discs did not produce acceptable
results and awarded the drive with a below average score.
The results with the DVD reading tasks were simply acceptable, since the Optorite
managed to reach the manufacturers specifications. The seek times for all tested
DVD media were very fast, just as with CD-R media, and this is another
plus for the drive.
One of the weakest points of the Optorite DD0405 was with DVD error correction.
Although some improvements have been implemented in comparison with the
previous Optorite drive, the new drive exhibited problematic behavior especially
with Dual Layer
DVD-ROM media,
focused in the second defective layer. Despite the fact that all tests ended
without errors, the Optorite needed much more time to complete these tasks.
The behavior, however, will not affect normal play back of DVD-Video (movies).
On the other hand there were no reading problems during the switch layer operation.
In comparison with the previous Optorite DD0401, the new version of the Optorite
has no changes with regard to the backup capabilities of protected games. The
ripping process of the games lasted much more that we expected while on the
writing
part, the Optorite
DD0405 managed to backup successfully only the oldest version of Safedisc protected
game we tested and this was done only when we used the Amplify option of the
recording software.
To mention some of the good points of the Optorite, we will report the performance
with the DAE tests. The reading speed for DAE media is 40x and that was confirmed
from all tests. Optorite was also fast on the ripping tasks, with support for
reading CD-Text, Subchannel Data and Lead In/Lead out information. The drive
was
awarded with
a perfect score on the DAE tests and managed to rip the audio protected discs.
With CD-R writing, the 40x maximum writing speed is the current maximum
available for a dual 8x DVD writer. The user will be able to record a full
data disc in about 3:10 minutes with the the quality of the disc being fair.
The quality check showed increased Pit and Land values, which were confirmed
by the C1 / C2 error measurements, at least with specific
CD-R media. Here, a new firmware should contribute to improve this behavior.
The HD-Burn function had no changes from the earlier DD0401. The ISO compilation
fitting 1.4Gb on a single 80min CD-R, was written successfully with the Optorite
drive, but the disc was not readable with other drives.
As a DVD writer, the Optorite wrote all certified 8x tested media
at the maximum available speed of 8x, while the quality measurements were slightly
increased being borderline, especially with the PI measurements. Despite
this, all discs were fully readable. Here we should add the contribution of
the latest
firmware release, v150E, that offered the drive very low recording times for
DVD+R (8x P-CAV).
Available on the market for less than $100, the DD0405 is a good solution
for DVD recording.
