20x DVD burners may become mainstream in 4Q 2007

Recommended Posts

"With Hewlett-Packard (HP) and Dell evaluating the feasibility of adopting half-height 20x DVD burners. A good chance of replacing 16x to become the mainstream writing speed of DVD burners in the fourth quarter of 2007."

 

20x DVD burners

 

What I want is a inexpensive (under $200.00) Blue-Ray that will burn regular DVD at 18X. I think I will be waiting a while. As for 20X, already have one.

Marlin,

what is the burn time difference between 16X, V 18X, V 20X?

 

What media can you get to burn reliable and consistent at 18X and 20X?

 

At what % completion of the disc does it achive 18X or 20X?

 

As you see in my signature. I only have a Double-speed CD-ROM drive, but my inquiring mind would like to know!

Actually, I have never really timed it, and a lot depends upon the software. Doing backups is slower than burning a movie as the backup is doing compression at the same time, whereis the movie burn is already rendered for burning.

As far as reliability, I have never had any real trouble with disks as I exclusively use Verbatim and TY only.

Also as long as the disks are marked at 16X, 20x should not be a problem. Maybe in a couple of days I wil set up a data DVD test and burn it at the different speeds and can give you a time.

Thank you, Marlin. In fact I'm still buying 16x BenQ clones!

 

Just how many computers to you have, CD, and which one are you online with?

 

At the moment four, all have online access if one plugs them in. The signature is a joke, you know that. I did own that pc in the early years though.

Speed tests. You got my curiosity up so I did them today.

Tests, although not scientific were all done using my Lite-On LH-20A1S(SATA), firmware 9L02.

DVD's were all TY DVD-Rs marked as 16X, DVDInfoPro stated that they could go to 20X.

Data burned was a DVD data disk comprised of MPGs totaling 4.35GB leaving approx 33MB available.

 

Burn speeds listed by Creator Class

16x = 21.6MBPS

18x = 24.3MBPS

20x = 27.1MBPS

 

Time was from when I hit the OK button to start the burn, until the cancel button changed to close. Only things I could figure would be consistent. All did tests did not really start burning for approx 35-40 seconds after hitting okay. Very consistent on that time

 

For 16x time 6 min 12 sec

 

Percent - Burn Speed

1 - 6.8x

20 - 9.5x

40 - 11.2x

60 - 13.6x

80 - 15.2x

90 - 16x

 

For 18x time 5 min 42 sec

 

Percent - Burn Speed

1 - 7.7x

20 - 10.7x

40 - 13.2x

60 - 15.3x

80 - 17.1x

90 - 17.9x

 

For 20x time 5 min 13 sec

 

Percent - Burn Speed

1 - 8.3x

20 - 11.6x

40 - 14.2x

60 - 16.5x

80 - 18.4x

90 - 19.4x

 

So every 2x will save approx 30 secs of burn time. All in all not bad times for any of them considering the amount of data being burned.

 

Hope this answered your question.

Excellent work Marlin.

May I copy and save it for future use?

Of course you would get the "credit"!

I'm surprised the TY -R go to 20x, I don't have a burner above 16x. I have used alot of 8x TY -R and 8 is all I get. The TY +R's I have always got a higher x rating.

Not terribly surprising

20/16 = 1.25

27.1/21.6= 1.25 (rounded to 3 significant digits, as are the burn speeds)

Allowing for the time lag before burning starts and probaly a little time to close, the burn times are also in the same ratio (but of course inversely so).

 

The wonders of simple maths :-)

jean,

could that simple math tell me the app that would be quicker, out of three or four popular burn apps? Then what app would have the best disc quality score when checked in a disc quality check tool?

Certainly, you may use it.

As far as burning faster than 16x, I tried a verbatim, and the highest speed it would let me burn was 16x. Did not not put it through DVDInfoPro though.
