Hi,[quote=tj1182;2027055]I have the burner said above, and I was wonder why it takes so long to burn something. It takes 9:43 to burn a 16x disc, DVD-R, DVD+R, but it takes 13:02 to burn a 4x DVD-RW, DVD+RW. [/quote]13 minutes for a 4x RW disc is okay, nothing to complain about.
The time for your “16x” burn looks as if it were written at 8x only.
This might either be due to the media you’re using (16x printed on a box of discs doesn’t say anything) or your USB interface may be the culprit.
To sort that out, I’d suggest to burn a disc using Nero CD/DVD Speed and post the screenshot here.
You might also use a DVD-R and check the “simulate” mark so the disc can be used later.
Also tell us, what USB controllers are used. Add-on cards do often max out at 12 or 16 MB/s which would allow max 8x burn speed.
There are also some poor on-chip controllers that aren’t much better.
In case you are running Windows XP, it is better to have Windows default drivers installed, since they are often faster than those from the chipset manufacturer or mainboard maker. Having SP2 installed, is another good
This picture below shows a simulated burn (attempted 18x) on a TS-H652D installed in an external USB enclosure, USB chipset is a recent Intel one. This drive is exactly the same hardware as your DRU830, but with Samsung OEM firmware, which does not support UDMA 4 (your Sony does, and the USB/IDE converter should be optimized for your drive).
This is the reason, why the buffer runs empty after reaching 13x speed causing a speed drop to 8x for the rest of the disc. Burn time was slightly below 8 minutes for a full disc (a real burn might be slightly slower than in this simulation).
