- Introduction
Plextor
is one of the few companies that used to adopt both IDE and SCSI connection
interfaces. For many years, the famous PX-40TS had become the de-facto CD-ROM
reader for SCSI interface. The last SCSI recorder from Plextor was the PX-W1210TS
model, and from that time, it seemed that Plextor would never re-release an
ultra fast SCSI recorder.
There were various reasons for this but the most important was the high cost
and the low demand/sales of SCSI recorders. At last, the 2003 find Plextor developing
a new fast SCSI recorder, despite the high competition of cheap IDE CD-RW drives.
What are the expectations from the new PX-W4012TS and how the drive performs
against its IDE brother (PX-W4012A)?
- Features
As we have mentioned in an earlier review, both the PX-W4012A/TS series support:
- ZoneCLV
recording technology
- VariRec recording mode
- PoweRec II media checking system
- Optimised PCB (power circuit board)
- Black tray
- Mt. Rainier support
- Up to 40X AudioCD authoring
- Specifications
The drive's features according to Nero Info Tool are the following:
PlexTools give us some additional information:
Something strange is that the PleXTools v1.18 didn't recognize the attached
Buffer capacity (4MB) and reported an "unknown" capacity. Probably
it's just a minor bug.
The drive supports 40X maximum reading / writing and 12X re-writing speeds.
The buffer is 4MB and the reading of CD-Text and CD+G are supported. Nero Info
Tool also reports that retrieving of C2 error information is supported but its
accuracy will be examined later. Mt. Rainier format is also supported. The following
pictures show the available reading/writing speeds:
After installing PleXTools v1.18 attached software, we can get more information
about the adopted technology for each reading/recording speed:
- Recording Technology
The drive supports the 40X recording speed with the use of Z-CLV recording
technology. As Nero CD Speed graph shows, the drive starts writing at 20X, shifts
up to 24x at 8mins, accelerates to 32x at 28mins and finally reaches the 40x
at 54mins. That gives a theoretical average writing speed of 31.06X when
using an 80min CD-R media.
- The package
We
got the European retail package which contains: the drive, a PDF manual in 16
languages, an RMA request form, a registration card, a quick installation guide,
1 blank CD-R (made by Taiyo Yuden), 1 4-12x HS-RW disc (actual manufacturer
Ricoh), an audio cable and mounting screws. The attached CDR software comes
from Ahead (Nero 5.5.x & InCD 3.3x) and "PlexTools" v1.18. The
bulk package contains: PleXWriter 40/12/40S, a manual in 16 languages, Plextor
Utility software (PlexTools), and an audio cable.
TPlextor offers a 2-year warranty (only valid in Europe, Middle-East and
Africa) and Plextor's "on-site collect and return service" (EU countries
+ Norway and Switzerland). The retail package costs around Euro 270, including
VAT, while the bulk version is expected at a lower price.
The PleXTools v1.18 software can be very useful for both amateur and experienced
users. You can adjust various settings of the drive, rip AudioCDs with probably,
the best error correction DAE software engine, author both AudioCD and CD-ROM
projects, can copy Audio/Data CDs (and AudioCD protected) and lastly test recorded
discs for reading errors.
- Looking at the drive
The front panel is almost the same as with the "older" PX-W1210TS.
There are four LEDs, two buttons (eject, play/next), and the "40/12/40",
"BPRec" and "High Speed" logos.
The operation of the front LEDs is the following:
- Disc Indicator: Shows a green light when a CD is loaded
- On/Read indicator: Shows a green light when the power is turned on and flashes
when data is being read from a CD
- Low-speed write indicator: Flashes orange when a CD-R is being written to
a speed between 1X and 24X, or when a CD-RW is being written to with a speed
between 4X and 10X
- High-speed write indicator: Flashes orange when a CD-R is being written
to a speed between 32X and 40X, or when a CD-RW is being written to with a
speed of 12X.
A special version with black bezel is also available, dedicated to users
who have a black coloured PC case. Both black and white versions are expected
to have the same price:
On the rear panel of the drive you will find the SCSI-2 connectors, the jumpers
for setting the SCSI-ID, the analogue and the digital audio output connectors
and of course the power connector. There is no attached fan as with the PX-W1210S
series.
The SCSI-ID can change with the appropriate set of the three jumpers, as it
is indicated in the following table:
The drive was manufactured at December 2002 and it comes with a hardware revision
TLA #0000
- Inside the drive
After removing the bottom screws we can see the internal of the drive. A big
difference with previous Plextor drives is the specific drive includes a warranty
sticker in the side, meaning if you decide to open the drive you will automatically
loose the warranty! Be careful! The drive is based again at SANYO chipsets and
uses various other chipsets without any obvious manufacturer ID.
- Installation
The PleXWriter PX-W4012TS was installed at an ADAPTEC 29160 with the default
SCSI-ID (4). The drive worked at Ultra SCSI mode (20MB/sec). After booting,
it identified itself as a "PLEXTOR CD-R PX-W4012S". We used
Nero v5.5.10, CloneCD v4.2.0.2 and Ahead InCD v3.51.91 for the recording tests.
The drive did not automatically reduce the maximum writing speed (40X) even
when we used a low quality media, but user will notice the increased recording
time. Also PoweREC cannot be disabled, as with the newest PX-W4824A series.
The following Nero picture shows additional information for the drive. After
this review was written, Plextor released a newer firmware update (v1.01) that
supposed to support the 1X writing speed. Despite our efforts we couldn't write
1X, even with the new firmware version.
2. Data Tests

Data Tests
- Pressed CD results: (Click to see the CD Speed 74
&
80min graphs)
The PX-W4012TS is slightly slower than the PX-W4012A series. The drive started
reading at 16.53X and ended at 41.8X with a 31.7X average reading speed.
The seek times of the PX-W4012TS are improved compared with the PX-W4012A
series, at least in the "Random" and "1/3" tests, since
the "Full Stroke" values are exactly the same.
- CDR Media: (Click to see the CD Speed 74
&
80min graphs)
With CD-R media, the PX-W4012TS is still slower than the PX-W4012A series
with a 31.5X average reading speed.
The seek times with CD-R media, are higher than the PX-W4012A
series.
- RW media: (Click to see the CD
Speed Graph)
Despite the fact that PleXTools mentioned that the supported read speed for
HS-RW is 32X max, the drive was faster reaching the 40X, giving a 31.68X average
reading speed.

CloneCD Reading
Tests
- Procedure
We used CloneCD and 3 original CDs - Serious Sam 2 (SafeDisc 2), V-Rally
2 Expert (SecuROM 2) and NBA Jam Extreme (PSX) - in order to test the reading
times of the drive. We also tested the reading performance with backups of the
original CDs, since the reading speed varies between original and backup media.
The following picture show the drive(s) reading/writing features as CloneCD
reports:
- PSX Pressed Media
We ripped the image to the HD with CloneCD using the default settings. The
drive needs 72secs to finish the task, while the PX-W4012A needs only 54secs.
- SafeDisc v.2 Results
The PX-W4012TS drive needed almost 6:32mins to finish reading. The PX-W4012A
read the same disc almost in the half time and therefore gets the first place.
- SecuROM v.2 Results
All drives can read SubChannel data from Data/Audio tracks. Here we can see
an improvement of the PX-W4012S, since it's slightly faster than the PX-W4012A
series.
5. DAE Tests

DAE Tests
- DAE features
- Pressed AudioCD
The PX-W4012TS and PX-W4012A drives have exactly the same DAE reading performance
(30.1X) with pressed discs.
- Audio CD-R media
With CD-R media, the PX-W4012TS is slightly faster than the PX-W4012A by
0.4X.
- EAC Secure Extract Ripping mode
EAC's secure extract ripping mode results, which ensures maximum produced
WAV quality. Note that for each drive we used the built-in detection function:

The condition of the disc can be considered as very bad, so the purpose of
this test is not to get the best results with zero read errors, but to estimate
the capabilities of the drive. The drive lowers the reading speed after 81%
and eventually returns a reading error.

CDR Tests
- Recording Tests
The PleXWriter PX-W4012TS showed a good behaviour compared with other Zone-CLV
recorders (Samsung SW-240B). The drive needs 204sec (3:24mins) to finish the
task. The PX-W4012A is slower only by two seconds. The below graph shows the
recording times for all the supported recording speeds above 16X, with Plextor
80min 48X (made by Taiyo Yuden) CD-R media:
As a notice we could say that the time difference between the 32X and 40X
is very low (7secs).
- Supported media
From our tests, we saw that Taiyo Yuden 48X, Mitsubishi Chemicals 48X, Fuji
40X, Imation 48X and SCK 48X media could be burned at 40X. With the new TDK
48X (white printable) we could write at speeds up to 32X. According to the Plextor
European
website, Hitachi-Maxell 4X-40X are also supported, while the USA website
has a more detailed
list of the supported media.
- Overburning Tests
The drive can overburn up to 99mins. This is an improvement over the previous
Plextor models.
- CD-Text Results
Can read/write CD-Text without any problems.
- CloneCD Writing Tests
The CloneCD software reports that the drive supports the DAO-RAW feature.
With the use of proper media, DAO-RAW writing can be performed at 32X.
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.
We used the drive as reader/writer at maximum reading/recording speed. Two discs
were burned for each game. One disc was burned with PadusDJ and the other with
CloneCD (Amplify Weak Sectors On). The results are posted in the following table:

The PleXWriter PX-W4012TS can backup discs protected with Safedisc v2.50.020
or older without the need of special software. The v2.60.052 build backups will
work only with the "Amplify Weak Sectors" option enabled, while the
latest v2.80.010 won't work, mostly since CloneCD has problems with it. Using
other software like Alcohol 120% or BlindWrite could be more efficient.
7. Writing Quality Tests - Page 1

Writing Quality Tests
- Page 1
We used Plextor 80min 48X (based at Taiyo Yuden) CD-R media and burned the
same AudioCD project (with CD-Text) at all recording speeds from 4X-40X and
with the "VariREC +0" option. Below you can see the 3T Pit & Land
Jitter graphs.
- 3T Pit results
As we can see from the above graphs, the 3T Pit Jitter stays below the 35ns
RED book limit at 4X ~ 32X recording speeds. In the 40X (Zone-CLV) recording
speed the drive produced higher jitter values after the 58min until the end
of the disc. The average 3T Jitter values for all recording speeds are illustrated
in the following table. The 4X recording speed produced the best results.
- 3T Land results
The 3T Land Jitter results are not very well, in the low recording speeds.
The VariREC +0 feature produced 36ns values and again the 40X recording speed,
after 58mins will give un-pleasant results. The16X recording speed produced
the best results.

The results with Taiyo Yuden 48X media for the low recording speeds are not
very well, especially for the 3T Land Jitter values. The VariREC +0 seems to
cause worst side effects than the normal (DAO) 4X speed, while the 16X seems
to produce the most balanced results. The 40X recording speed may not please
Audiophiles since the increased 3T Jitter value after 58mins is not according
to the RED book standard.

We tested the drive with a variety of other media in order to check the writing
quality performance. All media were burned at the 40X (Z-CLV) recording speed.
- 3T Pit results
As we can see from the above graphs, the 3T Pit Jitter exceeds 35ns RED book
limit for almost all media except from the CibaPlasmon 48X. The SKC 48X seems
to produce the worst results, while the Verbatim 48X media will perform well
until the drive enters the 40X writing speed. The Fuji 40X media also performed
well until the 76min, where it suddenly reached the 38ns. Below are posted the
average values for all tested media.
- 3T Land results
The 3T Land Jitter is similar with the 3T Pit results. The CibaPlasmon 48X
produced the best results, while the SKC 48X the worst. Below are posted the
average values for all tested media.

The results with various 48X media are at least interesting. The media that
worked best with the PX-W4012TS comes from CibaPlasmon and is rated at 48X.
The specific media produced the lowest 3T Pit&Land values and didn't exceed
the 35ns limit. The SKC 48X doesn't seem to perform well giving the worst results.
The Fuji 40X was a good performer until 78mins, where the jitter value reached
the 38ns.
9. RW Writing Tests
PleXWriter

RW Writing Tests
For the burning tests, we burned a full 74mins disc with all the drives.
The results are showed in the following chart. We used the maximum supported
speed for each drive.
Both the PX-W4012TS and PX-W4012A support the 12X writing speed with HS-RW
media. The drive will need 400secs to end the task and 35secs to quick ease
the media.
- Packet Writing Tests
We used Ahead InCD v3.51.91 for the packet writing tests. The formatted disc
had 534 MB of free space. We copied a 403 MB file (403.147 kbs) from a Hard
Disk (on the same PC as the writers) to the formatted RW media using Windows
Explorer (we dragged and dropped) and we completed the test more than once,
to eliminate any possible time measurement faults and user errors.
The PX-W4012TS reached the top with an 8.61X average writing and 17.35X average
reading speeds.
- Mt. Rainier Tests
For testing the Mt. Rainier performance, we used was InCD v3.51.91 by Ahead
Software. After the format process, we immediately started the recording process
(drag & drop). When the drive finished, we started the reading process back
to the HD. The PX-W4012TS performed well without any problems. The drive's reading
performance was higher than in the normal Packet writing mode, while the writing
speed was slightly lower (7.49X).

Although the drive accepted the EasyWrite test suite commands it didn't fulfil
the basic PartA v1.60 tests. We are expecting Plextor to improve this with a
future firmware update.

The PleXWriter PX-W4012TS comes to fulfill a specific market where most manufacturers
avoid entering so far. Although the SCSI interface used to be the no1 choice
for power users, today it has been neglected and set aside by the evolution
of IDE devices and the fast USB2.0 and FireWire interfaces. The increased cost
of SCSI devices gave the manufacturers no other choice but to drop it and continue
evolving the IDE devices. Plextor comes to change that with the PX-W4012TS.
The drive worked in the most of the tests either equally or slightly slower
than its IDE brother (PX-W4012A). All the familiar technologies are present
(BURN Proof, PoweRecII, Mt. Rainier, VariRec, 4MB buffer) as in the IDE model.
The drive can rip Audio CDs in a high speed and at the same time, is able to
handle Audio protected discs. Reading and writing of CD-Text is not a problem,
while the overburning limit has been increased to fully support 99min discs.
The package is poor compared with the IDE model (one piece of CD-R instead of
five pieces of the PX-W4012A) and comes with a 2-year warranty for the EU buyers.
Listing the negatives, we must note the high Jitter values at the maximum speed
with various media, while the error correction capabilities could be better.
In addition, although retrieving of C2 error information is present its accuracy
is not high. Users who wish to backup their discs will not be satisfied by the
limited EFM hardware correction, but this is a common characteristic for all
drives that use SANYO chipsets. As a last note we could say that the price of
the drive is not very compatible, since very cheap 52X solutions can be found
at a price around Euro100.
Summarizing our thoughts, we can say that we expected a better overall performance
from the PX-W4012TS, considering the high price of Euro270. The PX-W4824A is
available in almost half this price and performs faster in the most of the tests.
Of course the SCSI interface is what some users have been requesting from Plextor
to implement, so we can assume that they will give the extra money to buy it
:-)
