Max Burning Speed

[zacksz]

This has probably been asked many times.

I have a Plextor PX-760A Drive

I am using Memorex 16x DVD+R Disc's

 

Why is my average write speed so much slower than 16 X?

At first it was even slower so I checked the Plextor web site and I saw a Firmware Update, this did help it speed up but I would expect somewhere closer to 16 X.

 

 

I am trying to get this tuned up ASAP I have to burn 30 Copies of a DVD in the next couple days.

 

Other than that I am very happy with the product.

16x is only reached at the end of the disc.

 

The quality of the media also plays a part. The drives are clever and will slow themselves down if they think the burn quality isn't up to scratch.

 

So you need to be burning a FULL disc, AND onto decent media to get the full 16x / 18x etc.

[Shamus_McFartfinger]

My 2c:- 16x/18x is the maximum speed attained at the outside track under lab conditions. i.e. Perfect conditions. That means perfect media, perfect drive, perfect hardware connections, top-of-the-line PC with no "baggage" running in the background to slow things down etc.. etc..

[volvofl10]

and its like the car adverts , where our latest model does 99 miles per gallon

 

as long as its downhill on a dry day with a gale force 10 wind pushing you ................oh and theres a letter Z in the months name

 

id be happy to attain 11.3x regularly

[Shamus_McFartfinger]

So would I but I've still got a hundred Verbatim MKM-001's to get rid of before that happens.

[Shamus_McFartfinger]

Hmm... a quick look at the thread doesn't impress me that much. Some of those claiming to burn at 18x actually burned at 4x, 8x or 12x. Not what I'd call exciting. Particularly when the maximum speed was attained near the outer edge of the disk, just like we said it does. Physics is a cruel mistress.

[LOCOENG]

The best I could ever do was 13X and change...and since you can only achieve the higher speeds towards the outside of the disc the measurement is best taken in the amount of time it takes to burn the entire disc. This would give you the highest average speed and I haven't found that burning at higher speeds to give that much less in quality, only a slight difference.

[Shamus_McFartfinger]

Agreed. A burn @ 8x is still going to be completed in under 10 minutes on single layer media. The quality will be good, it'll verify properly and everyone will be happy. At 16x you're asking the burner to write something like 22MB/sec which is alot. BTW, I just had a quick look at your forum and it looks pretty snappy.

[LOCOENG]

You talkin about BB? It isn't much...but it's all I have. LOL

[zacksz]

Thanks for the Input, sounds good to me I just was checking. The disc I was burning to test where only a half a disc and never reached the end of the disc. I guess my speed isn't that bad.

[zacksz]

Who Makes the Best Media?

I guess based on my results the DVD's I have are OK.

[cornholio7]

verbatim and taiyo yuden are the best. dont take our word for it , look here http://www.digitalfaq.com/media/dvdmedia.htm

 

tests done on this forum on your media http://forum.imgburn.com/index.php?showtopic=580 show it to be inconsistent

[spinningwheel]

verbatim and taiyo yuden are the best.

 

 

[volvofl10]

but I would expect somewhere closer to 16 X.

 

 

EDIT

I 23:39:10 BURN-Proof: Enabled

I 23:43:33 Average Write Rate: 10,977 KB/s (7.9x) - Maximum Write Rate: 15,622 KB/s (11.3x)

try one with out Burn Proof enabled , be warned though, it may result in a coaster . Burn Proof slows down the write process if it thinks the drive cannot work at the set speed for any reason . the I/O speeds and connections are the usual things to slow a burn down like Shamus told you earlier

[LIGHTNING UK!]

I think you're confusing 'Burn Proof' with 'WOPC / SolidBurn / etc etc'

 

Burn Proof just tells the drive to wait for more data if it's buffer runs out - rather than erroring out and creating a coaster.

 

The only problem here is that only just over 1/3 the disc was burnt - hence max speed would never have been reached.

[volvofl10]

if the disc had been full , wouldnt your explanation slow the overall average write speed down anyway though when the buffers wait to be re-filled ?

 

/me thinks it could be a "close but no cigar "one here

[chewy]

Hmm... a quick look at the thread doesn't impress me that much. Some of those claiming to burn at 18x actually burned at 4x, 8x or 12x. Not what I'd call exciting. Particularly when the maximum speed was attained near the outer edge of the disk, just like we said it does. Physics is a cruel mistress.

 

 

page 2 had some decent burns that hit 16x, even by a noob

 

of course the purpose of the thread was not burn as fast as possible, but to have good burns in a timely manner

[LIGHTNING UK!]

Yes, it would lower the average, but you'd still see the 'maximum' reach the expected 16x - and that's enough to know it's working fine.

[blutach]

The MCC-004s I use, attain 16x at around the 3.5Gb mark. The firmware of my LG 4163B allows it to run at constant spin rate (full CAV)

 

 

I also have no issues with enabling BURP (for some reason I prefer this acronym).
