Audio testing
 

Audio read performance:

To test the audio performance we downloaded EAC.
This utility enable accurate audio grabbing and reliable conversions.

One good thing about EAC is the integrated drive detector to detect the various features of your drive.



The EAC interface - Simple and accurate


We select drive Options to optimize our writer and to detect the options.


Extraction method:



The detected functions of the Plextor 24/10/40 IDE


We are going a little deeper into these properties:

  • Caching: If your drive caches the audio that was just read, it would be a problem to read this data again in order to compare both extractions to find out if they match. In that case this option has to be enabled, so that EAC will clear the cache by overreading it.
  • Accurate stream: This option should be set if your drive has an accurate stream , meaning that it won't jitter, thus no jitter correction has to be performed anymore.
  • C2 error info: Some newer drives are able to return C2 error information besides the actual audio data. In this case EAC doesn't need to read all data twice anymore, wich will result in an increased speed.



    The Plextor returns C2 error information according to the build in testprocedure...



    Here we see the new Plextor's ideal settings for audio grabbing using EAC


    The drive's read commando's:

    Because in the beginning there was no real drive-standard, most manufacturors used their own commands to read audiodata from CD's. Due to this fact EAC knows many read commands and has a build in detection system to select the appropriate command for each drive.


    The drive detection methode told us that the Plextor 16/10/40 uses the "read command D8".

    Offset/speed:
    We did the 'detect sample offset correction' after creating a test CD for this feature. If we want to find an exact location on an audioCD it isn't that simple as a normal data CD. Due to the lack of some extra data to calculate the exact position on an audioCD it is not possible to go to a predefined position. It will only be in the area of that position. Usually it is a few samples before or after that position.
    With the offset correction you are much more accurate in locating the exact position.

    The offset value of the Plex 24/10/40A is +68





    The selection of 'allow speed reduction during extraction' helps a lot when there are various errors on the CD. Finally we select the CD-Text function.

    The folowing preferences were also detected.

    Excellent and comprehensive review. You leave us with only one question:

    Where did you get the 1.02 firmware?

    It is not posted on any of Plextor's websites yet.

    Please share a link if you can!
    Excelent review of this great piece of hardware.
    I think i am going to get one myself to :4
    Where did you find the 1.02 version of firmware?
    Firmware 1.02 is not offically out yet.

    We had permission from Plextor to publish the results of this new firmware before it is offically released.

    It will be available soon! But we wanted to let u cdfreakers know the results before it is even released! :)
    I make a back up of NHL2002. Firmware 1.01; 16 minutes!!!!

    The game work perfect. Great burner:)
    How can i find out wich firmware revision i have on my Plextor 24/10/40 in Windows XP
    How can I copy NHL 2002 ?? It has Safedisc 2 Protection, im reading with fast error skipping, intelligent bad sector scanning and disabling read error reports. I upgraded to 1.01 firmware.
    Use your Plextor for read

    Fast error skip
    Setting:

    read speed max: 4
    read retries: 3
    error corections: none

    Stay tuned
    compare to 12x-10x-32x scsi, which is faster?
    What TLA# is on the drive you tested?
    I have one with TLA#0000 at work and with TLA#0100 at home, didn't have a chance to test any of them with SD2 yet.
    Where can I find 1.01 Firmware ?
    Plextor firmwares are here:
    www.plextor.be
    Tested both drives with TLA #0000 and #0100, firmware 1.02, both copy SD2 fine.
    Hi!

    I read your review and found one strange thing; As far as i know, Plextor 1610a does support only RAW reading but no sub codes. According to review you were able to perform sub code reading in LaserLock and SecuRom tests. I have the PX-1610A and haven´t been able to perform sub channel read with CloneCD or BlindRead. Both apps inform that the 1610 is not able to read subs. Am i stupid or why is it not working? I´ve used fm 1.02 and 1.03. With my Toshiba CD-Rom sub codes work fine with both apps.

    PS. do you have a clue where can i find older firmwares to PX-1610A (1.0, 1.01, 1.02)?
    hoi xosak

    thanks for your test,
    but it seems that TLA#0100, can't copy protected audio cd's and the TLA#0000 can copy protected audio cd's.

    I do not know this is true, but it is mentioned on several forums on the internet.

    Does any body know with what TLA number the test on cdfreaks is made with
    I make a perfect copy of NHL 2002 on my PX_W2410TA tla #0000 with Clone CD in 17 min. I use Clony XL for setting's. :4 PLEX IS THE BEST :)

    Bought one and it is an excellent writer haven't had any problems yet :)
    I'm using mine for a week now and loving it.

    My previous burner was a Sony CRX-140s and was OK - but the Plextor is in a different league alltogether! :g
    Plextor rulez!!
    After i read this review I am a Believer again. Great test. Great drive.
    :)
    :( I could not copy fifa 2002 with 241040a.....only works if daemon or hide cdr is enabled..ideas?
    The LiteON drive is CHEAPER and JUST AS GOOD! Convert, you fools!
    Have both the Plextor and the Lite-On 24x !!
    My favorite by far is the Lite-On(Damn Best Writer I ever used)Lite-On should have gooten the higher score over Plextor; but I guess some people's old habits dye hard !!! Enjoy !
    If you want your reviews to be taken seriously you guys really need someone who understands the english language and can spell to edit these reviews.
    GREAT review..
    I am looking now for a new burner, and I was thinking of maybe buying the cheaper LG or Lite-On ones... but afetr your review.. .well .. let's just say I can't find any excuse not to buy a nice Plextor...
    Thanks Again!!
