Taiyo Yuden 8X vs 16X

[ustishrike]

I have a Samsung SH-S203B SATA drive and I use Imgburn exclusively for my burns. Are the TY 16X better than the 8X with this drive? How do I use the diagnostic tools to check my burns and what are the most important things to look for when evaluating which is a better burn. Thanks for any help .

First make sure your burner has the latest firmware available. You can use DVDInfoPro and Ner0 DiscSpeed to do quality scans on your burned discs.

[ustishrike]

I have the latest firmware and DVDInfo Pro. I have examined the Imgburn Graph data but am not really sure what I am looking for.

Look in DVDInfoPro's main window, there's a button there for quality scan.

[ustishrike]

I ran the PIPO scan on an already burned disc. Is that the right one? The quality rating said 99.0%. Is that good? I couldn't make much of the graphs. And it did not test for jitter. Thanks for your help, BTW.

Someoe hasn't looked in our Media section...

[ustishrike]

Thanks. I'm going there now. However, in general, is 99.0% a good quality rating? Thank you for your time.

Thank you for referring me to the media section, it was very enlightening.

[cornholio7]

without the jitter measurement its not a true result but assuming the jitter was under 10% for the whole burn , your 99% would be fairly accurate

[ustishrike]

I'm assuming that my drive does not support the jitter function? So I should strive for for a better percentage, since you described the result as "fairly" accurate? I'll post a snapshot in a few. I do have Nero too, should I try DiscSpeed?

it looks good

 

try cd speed , see if it supports jitter on your drive

[ustishrike]

Thank you for your time, Cornholio. I'll give it a try.

[ustishrike]

CD Speed won't do a quality scan at all with my drive and I just flashed it. The firmware update was very recent too. I like the drive, but.... Oh well, maybe the next update will address it.

[ustishrike]

Any suggestions on quality diagnostic tools other than CD Speed (Nero) and DVDInfoPro?

[cornholio7]

its not the programme that has a problem showing jitter, its your drive, scanners that show jitter are ones such as benq 1640 and 1655 and some of the newer lite-on drives, i am not sure of those lite-on model numbers that can, maybe one of the other members knows.

dvdinfopro and cd speed are about the best there is for scanning

[ustishrike]

That's what I was figuring, Cornholio, but I thought I'd ask. I'm thinking, like you mentioned, that the quality rating isn't as accurate without the jitter evaluation. Could a future drive firmware update address this sort of thing, do you think?

[ustishrike]

I've found out something interesting. Slower is not necessarily better. I burned identical data on TY 16X discs (T03) at 4X and 8X. As you'll see below, the 8X is a significantly better burn than the 4X. I'll pick up some TY 8X discs (T02) and make the same comparison and we'll have the answer to the title of this thread.

 

OOPS! the attachments didn't work. I saved them as DIPX files instead of PNG files and they didn't insert properly. I'll post the graphs very soon. Sorry.

Here they are:

With DVDInfoPro, you should set the read speed to 4x. It gives more accurate values.

 

[ustishrike]

Thank you, Cynthia. I'll do that in the future. Although, for a more accurate comparison should I scan at 8X when check my T02 burns?

[Cynthia]

With DVDInfoPro - scan at 4x and if you use the Nero DiscSpeed - scan at 8x. This is for all type of DVD discs.

 

Scanning with Samsung + Nec/Optiarc (non Lite-On based Optiarcs) - usually gives a little bit to good result. But as long as you don't compare apples with bananas and just compare your own burnings at various write speeds - it should give you a clue on which ones (write speed) is the optimal for the burned discs. Don't forget to try 6x - it's very often a "forgotten" speed, that can give very good results.

 

I doubt that jitter scanning will be possible will your current burner. It's something with the chipset that needs to be the right one for allowing that.

 

If I'm not totally wrong - all the later models of Lite-Ons (the iHAP/iHAS models) - support jitter scanning. Also some older models - like my own DH-20A3H.

Hi,

 

You asked several times if 99% is a good result and logically it could only be better if you got 100% but as Cynthia has alluded to, the real question is how reliable are the results from your Samsung.

 

You can find more information on quality scanning and also how to use CD/DVD Speed with your Samsung in the following post if you're interested....

".... Some drives give good results (comparable to other well-known scanning drives), some others are questionable. So take the scans with a grain of salt unless you were able to verify them with another drive like a Liteon or Benq DVDRW."

Thanks Jeff, I'll check it out.
