DVD Burning 8x is Slow |
|
|
I have a Liteon SOHW-1673S DVD Burner.
Burning at 4x is fine, and takes about 12mins.
On 8x it is taking about the same amount of time maybe a minute
quicker. It seems the buffer level in nero is emptying too quickly
therefore making the writer pause for more data.
I am using sony media; I think the cause maybe the PC it is an old
P3-500 256mb machine, and I am not sure if this spec is fast enough to
do DVD burning at 8x.
DMA is switched on and the DVD writer shares the channel with a Liteon
CD burner.
Now before I start looking at newer faster machines I was wondering if
anyone can confirm if a P3-500 is too slow for 8x burning, or prehaps
there maybe another cause.
TIA

It's probably marginal. Does the DVD drive's specs list a minimum
speed? Several factors could include lots of small files, which causes
lots of seeking, or a slow HD.
I think some software have the ability to write an image to your HD
first, then burn from that image. That might help as it only has to dump
directly to the DVD instead of copying and processing files on-the-fly.

Sorry I should have said, I was burning an iso image at the time.
Minimum cpu spec for the drive is pentium III 450.
The hard drives dma are ultra dma 33. |

CPU speed is not the issue - the CPU is essentially in idle for most
optical writing. (There are exceptions when you do related jobs on the
fly such as decompressing MP3s.)
Probably causes are effective HD speed, bus loading and fragmentation
leading the list. You did not identify the job you're trying to do. For
example, if you're copying a disc on the fly, your results are not at
all surprising; read speeds in practice are not high enough to take
advantage of write speed. As you have discovered, buffer-underrun
prevention does take time so if you invoke it often it's common for
total write time to increase as nominal speed goes up.

Data rate for DVD 8x: 10.57 MB/s
UDMA-33: 33.3 MB/s
UDMA-33 interface is more than adequate for 8x burning, but your hard
disk Sustained Transferred Rate (STR) may be on the border line.
Typical STR of 5400rpm drive is 12MB/s, for example. Try with dramatic
increase in the buffer size of Nero: [File, Preferences], Cache tab. |
