AOpen COM5232
/ AAH - Page 1
Taiwanese
manufacturer, AOpen, has expanded its product line to include motherboards,
graphics cards, sound cards and other PC peripherals. For optical storage
devices, AOpen has released a new IDE combo drive labeled
as AOpen COM5232/AHH..
- Features
The
drive reads the following formats: DVD+R/RW, DVD-R/RW, CD-RW, DVD, CD. AOpen
features the Just Link technology developed by Ricoh to prevent buffer under-run
errors. During the writing process, the drive calculates the optimum laser
power,
adjusting it in real-time to compensate for a dirty disc.
JustLink
The amount of data accumulated in the buffer memory is continually monitored
during the writing process. If for some reason, the data transfer speed from
the computer falls below that of the drive's writing speed, the amount of data
accumulated in the buffer memory will also fall. When the amount of data in
the buffer memory falls below a certain level, and a buffer underrun error will
occur should writing continue, writing is intentionally suspended. During this
time, when writing is suspended, data transferred from the computer has a chance
to fill the now depleted buffer memory. When enough data has accumulated, writing
is once again resumed from the point directly after which it was suspended,
and monitoring of the amount of data in the buffer memory is recommenced.

- Retail package
The
drive is well packaged. Apart from the
AOpen combo drive itself, the user will also find two extra faceplates
(one black and one gray), along with a printed guide for assembly and
installation and mounting screws. There are also, NeroExpress for writing
and PowerDVD for DVD-Video playback.
Unfortunately the package does not come with blank media.
Removing the screws and opening the drive's cover voids the drive's warranty.
For reference reasons, we post the following pictures.
The controller chipset is from Taiwanese Manufacturer ALi, the M5731 DVD-ROM
+ CD-RW Combo Controller, as the above screenshot shows. The
previous AOpen 5232 writer had used the Ricoh
chipset.
- 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 "AOPEN COM5232/AAH". All reading tests
were done with firmware vT108.
The following pages include test results for the AOpen drive in comparison
with two other combo devices, the LiteOn SOHC-5232K and NU DBW-521.
2. Data CD Reading Tests
AOpen COM5232 / AAH - Page 2
Data
CD Reading Tests
To test the reading performance of the AOpen, we used the latest version of
NeroCDSpeed with different media formats depending to the test.
- Pressed CD results (Click
for CDSpeed results)
To check the reading performance of the AOpen with pressed CD media, we used
NeroCDSpeed and a data pressed disc.
The AOpen drive managed to return quite acceptable reading speeds,
as indeed did all the drives as seen from the screenshots.
The drive used CAV reading strategy
and
CDSpeed
reported an end speed of 53.61X. The test finished, reporting
the access times for a pressed CD-ROM and the results are summarized on the
seek
times
graph.
Although there is not much between the three drives, in general the AOpen drive
was slightly slower and had higher seek times.
- CD-R results (Click
for CDSpeed results)
To check the reading performance of the AOpen with CDR media, we used NeroCDSpeed
and a clone of the previous tested pressed media.
NeroCDSpeed reported a very slow start reading speed for CD-R media.
The test started at only 6.15X but the speed increased to 24X after only
few
sectors
and under CAV the test finished with an average speed of 38.96X. The transfer
rate graph shows that the AOpen drive gave back slightly slowest reading speed
among the
three
devices but the end reading speed meets the manufacturers specifications and
so can be considered as accepted. The seek times of AOpen, with CD-R media,
were about equal to the other devices but as the seek times graph shows, AOpen
proved faster than LiteOn in all three modes.
- ReWritable Media (Click
for CDSpeed results)
To check the reading performance of AOpen with US-RW media, we used NeroCDSpeed
and a disc from Mitsubishi Chemicals.
AOpen gave back the lower reading speed at all reported measurements, as the
above graph shows. The tested device read the disc under CAV reading strategy
but the reading speed stayed constant at the last tracks and the test finished
at 40.14X end speed.
3. Error Correction Tests

This test disc, the ABEX TDC-726, is a much easier test disc. While the total
error count is low, at only 238, the norm is no errors, especially from the
better drives. EAC awarded the drive with a total score of 91.1 points.
This is an acceptable score, we can even consider it a very good score and
certainly better than average although the performance can not be ranked
amongst the best.
- 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 reading music abilities and reproduce
it completely. Five tracks on the disc contain a progressively difficult sequence.
These tracks are referred to as Check Level-1 through Check Level-5.
The
tracks are reproduced (played) through a software multimedia player (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 drive.

DVD reading tests
- Single Layer DVD-ROM
(Click
for CDSpeed results)
To check the reading performance of the AOpen drive with single layer DVD-ROM,
we used Nero CDSpeed and the 820A test disc from ABEX.
All three devices returned an end speed of over 16X. For the AOpen, CDSpeed
reported P-CAV reading strategy and the speed versus revolutions graph shows
some problems from around the 3 GB mark and onwards during the reading
process.
The AOpen drive returned faster seek times than both the LiteOn and NU for
single layer DVD-ROM. The full seek time for the AOpen was 149ms.
- 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, where lies the
beginning of each layer and progressing outwards towards to the outer tracks
for each layer. The tools for this test are Nero CDSpeed and Abex 840 test disc.
The AOpen proved quite a deal faster than either the NU or LiteON drives
when reading dual layer DVD-ROM media. The NU and LiteOn Combo drives had very
similar speeds for all of start, end and average speeds.
The AOpen combo drive was also faster with the seek times, especially with
the full seek time where it was 35ms faster than the NU drive, and 56ms faster
than the LiteON.
- 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 AOpen used CAV reading strategy for the OTP dual layer DVD-ROM reading
test. The above screenshot shows that the drive had a problem during the switchover
from the first layer to the second.
- DVD Ripping Tests
We measured the DVD-Video ripping speed for the LiteOn using the latest version
of DVD Decrypter. The DVD Video title is the "Matrix" pressed DVD-Video.
Although the AOpen reported the fastest reading speeds amongst the three
devices for both single and dual layer DVD-ROM media tests, in the DVD ripping
tests with DVD Decrypter, it proved the slowest ripper with an average read
rate of only 3.0X while the maximum read rate was 5.125 KB/s (3.7x)
- DVD Recordable / Rewritable
reading Tests
The chart below shows the Nero CDSpeed average reading speed results with
the following media by MC:
The three devices of the roundup reported almost the same average reading
speeds with all four tested DVD media.
5. DVD Error Correction Tests
AOpen COM5232
/ AAH - Page 5
DVD Error
Correction Tests
In the following tests we examined the DVD reading capabilities of the tested
device 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 first test disc from the Abex series was not a problem for the AOpen
combo drive. The drive finished the error correction test with a fast end speed
and CDVD
did not report
any read
errors. Notice however, in the region with scratches of larger dimensions,
the drive changed speeds often (dense collection of yellow dots a little after
the 1.000.000
sector) in its attempt to overcome the defects
ABEX TDR-825
This
is also a single sided, single layer DVD-ROM with 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.
Once again the AOpen COM5232/AHH finished the test without errors and with
fast reading speed.
- 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 comes from CDVD and shows that the tested device read
the effected dual layer DVD-ROM without producing any read errors. In first
layer the drive
encountered a bit of a problem half way through the defective region but
managed to overcome this. The second layer which
has
the same defects
as the first, was read without any deviations to the reading speed.
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 (micrometers).
Here too, very good error correction performance. The
screenshot shows temporary changes to reading speed at the beginning of the
test and
smooth
reading process until the end. The overall performance of the AOpen could
be considered as quite acceptable.
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.
NeroCDSPeed reported CAV reading strategy with fast average speed. During
the error correction test, no errors occurred but the drive changed reading
speed momentarily
after changing to the second layer.
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 micrometers
high fingerprints.
Fast and smooth reading process without reading errors, as the above screenshot
shows.
6. Protected Disc Tests
AOpen COM5232 / AAH - Page 5
Protected
Disc Tests
- Reading Tests
To create an image of the various protected titles onto a hard disk, we used
Alcohol 120% and the appropriate settings, depending on the protection type
of the inserted discs. Below are summarized the capabilities of tested device,
according to CloneCD software. The summary below shows that the drive supports
writing of CD+G under RAW DAO:
The game titles we used to test the reading speed for each protection scheme
are given in the table below:

7. DAE Tests
AOpen COM5232
/ AAH - Page 7
DAE Tests
- Pressed and CDR AudioCD results
To check reading of a pressed disc with the AOpen COM5232
we used
a pressed audio CD and NeroCDSpeed.
The reading test finished with a reported average reading speed of 33.20X.
The drive used CAV reading strategy and the software reported acceptable
seek times.
To test the ripping speed of the AOpen we ripped the contents of the same
audio disc to our hard disk, using the CDDAE software. For CD-R media we used
a clone of the pressed disc.
The LiteOn produced the fastest average ripping speeds of the comparison.
The above graph shows that AOpen was the slowest device in the audio pressed
ripping process.
- Advanced DAE Quality
The above graph shows that the LiteOn was the only device that wasn't
awarded a quality score of 100 (perfect). The AOpen had the fastest
average speed at 35.74X while as the screenshot from Advanced Dae Quality
shows,
the drive is able to read Leadin/Leadout, CDText information and Subchannel
Data.
- Support of 99mins
AudioCDs
AOpen ripped all disc contents of the 99mins AudioCD
- 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.

8. CD Recording Tests
AOpen COM5232
/ AAH - Page 8
CD Recording
Tests
- CD-R Writing Tests
To test the writing speed and writing method of the drive with CD-R media, we
used
a
blank
80min
CD-R disc from TY and Nero CDSpeed.
NeroCDSpeed reported that the AOpen drive reached the manufacturer's specifications
of 52X maximum writing speed. The burn process started at 24X, CAV and
finished
with an end speed of 52.03X
-Recording Times
We created an 80min data compilation with Nero Burning Rom and recorded it
on a 700MB disc.
The graph shows the time that each device needed to burn the 700MB compilation.
The AOpen and LiteOn drives finished the task at about the same time while
the NU proved slightly slower.
The above screenshot summarizes the burning times for each device at the
supported speeds, from 24X to 52X. We notice that the greatest difference
between the drives occurs at the 40x writing speed where the NU seems to have
performed exceptionally badly. Other than this, there isn't a lot between the
drives.
At the
lowest
speed of 24x, all
three
writers reported almost equal writing times, while at the maximum speed
of 52x the LiteOn drive proved fastest. The NU was fastest at 24x and 32X,
while the AOpen had
the fastest
writing time at 48X, and overall reported
quite
acceptable times at all tested speeds.
- CD-RW Writing Tests
To check the writing performance of the drive with RW media, we used a blank
32X USRW 74min CD-RW disc from MC and NeroCDSpeed
As NeroCDSpeed reported, the AOpen Combo device burned the rewritable media
with P-CAV writing strategy and had an end speed of 32X. In the comparison
for burn times and full erase with RW media, the AOpen drive returned the fastest
burn time, being 34 seconds faster the next best, the LiteOn. In the full erase,
all three drives had similar times.
9. Writing Quality Tests - 3T Jitter Tests
AOpen COM5232 / AAH - Page 9
Writing Quality Tests - 3T Jitter Tests
The AOpen is an all in one device. The drive is able to read DVD-ROM media
and at the same time is a fast CD-R writer with a maximum supported writing
speed of 52X.
The writing tasks proved that the drive managed to write media at
52X but just as important is the quality of the
writing.
To check this, we measured
the
Pit and Land values of all written media and summarize the results on the
following graphs. We need to mention however that of all the
tested media, only four were written at the maximum speed of 52X
- 3T Pit results media
The Pit values for all four media measured, are on the high side. Only
BenQ reported an average Pit value under the 35ns RedBook limit. In general,
no media managed to stay within the 35ns limit.
- 3T Pit results media
The average Land Jitter values for all media
are also high, with all values increasing as reading progressed towards the
out tracks on the media's surface. Again, no media managed to stay below the
35ns limit.

Writing Quality Tests - C1 / C2 Error Measurements
The C1 / C2 error rate was measured for the same media used in
the previous jitter measurements. The software used was Plextools
v2.13 and the
reader was the Plextor Premium drive.
-
Memorex 52x recorded at 52x
-
Traxdata 52x recorded at 52
Apart from media appearing in the graphs above, we checked the writing
speed of other manufacturers media. However, the AOpen drive did not support
52X maximum writing with
most
of them.
Plextools
recorded low C1C2 error measurements with most of the above media, except for
Traxdata and Memorex, indicating that the drive is capable of quality writing.

Only a few days ago, AOpen released a combo drive with a maximum supported
writing speed of 52X, the AOpen COM5232/AHH. This is an all in one device,
supporting CD-R reading/writing while the user is able to use the same device
to playback and
rip DVD-ROM's.
The drive came to us in a retail version bundled with Nero Burning Rom and
PowerDVD although unfortunately without any blank media. We made several tests
in order to check the capabilities of the device.
The AOpen drive proved fast in the CD-R and CD-ROM reading tasks. Using
CAV reading strategy, the drive easily reached the
52X maximum reading
speed as given in the manufacturer's specifications. The seek times were slightly
increased in comparison with the other devices used in the comparison
but were still quite acceptable. For the CD-RW format, the supported reading
speed of 40x was reached
once again
using CAV
reading strategy.
We also checked the CD error correction abilities of the drive.
We used EAC software and media from Abex for the tests. The drive needed
more
time than the competition's drives but managed to get a good average score
at 87.75 out of 100.
The DVD reading tests showed that the AOpen is a fast DVD reader with quite
low seek times but was not as fast as we expected in the DVD ripping department.
The combo dive read all writable, rewritable and pressed media fast, with
consistent performance but
reported only 3.7X maximum ripping speed.
The drive also proved that it can be relied upon to playback scratched
and defective DVD media. The drive managed to read and finish all tested media
without
problems
or read errors.
One of the weaknesses of the AOpen was with backups of protected
games. We checked the time that AOpen needs to make images of various
protected games and then we burned those images. AOpen was very slow on the
image making process, especially with SafeDisc protected game where the
drive needed about one hour to finish the task The image burn process was quite
disappointing
since the AOpen drive managed only one
valid disc, that with the SD v2.51.020 protected game.
Although the AOpen COM5232 proved weak with protected
game backups, it recognized, played back and ripped all protected audio
discs we tested. On
the
other hand, the DAE speed of the drive was 32X and not 40X as expected but
the drive was awarded with a perfect DAE quality score.
Users who choose to purchase the AOpen COM5232 are those seeking
fast writing times. The drive supports the maximum currently available writing
speed of 52X
under
CAV writing
strategy. The drive managed to write a full 80min audio disc in about
2:39min, a time that is really fast but the compatibility of the AOpen was
restricted. We used many different media from MMC, MC , TY, Ritek and other
manufacturers, but only four brands successfully burned at the
maximum supported speed
of
52X while
the
speed with the others was lower.
Despite the writing time, what matters is the quality of the written media
and that was the next thing we tested. Almost all written media returned
low
C1C2 errors but Pit and Land values were all above the 35ns limit.
For all media that returned increased values, since there
was a possibility of errors during reading, we used Plextor
premium to check them but the tests finished without reporting problems.
The drive is already in the market at the price of $50.
