Why is it taking 90 minutes to burn a dvd?

Somebody save me from throwing my computer against a wall. I have a system that I use for dvd duplication. It has a Gigabyte GA-MA69GM-S2H motherboard, with an AMD Core 6400+ (64-bit) processor running at 3.21GHz. The OS is XP Home. I have 4 gigabytes of Crucial RAM installed. I have (4) Samsung SH-S223l SATA dvd burners installed, and a 500GB IDE Western Digital hard drive.

When I burn one or two dvds simultaneously, burn times are normal, about 6-7 minutes at 12x. When I attempt to burn 4 discs at the same time, it takes over 90 minutes. This shouldn't be. It's very frustrating. I have tried versions 6, 7, and 9 of Nero Burning Rom. Nothing changes. Can anyone shed some light on this?

 

"This shouldn't be."

Looking at your hardware, you are incorrect in your assumption.

Please see this thread:

One of your bottlenecks is a single HDD going to 4 burners.

 

In reading that thread, I have to say my situation is a bit different. I am not using any external burners, and I am not using multiple applications of any burning software. I use Nero and I have it set to burn on multiple drives. I just have to select which burners I want. And the bottleneck is not a single HD supplying multiple data streams. I have built ummm-teen 4-burner systems, but they all had IDE burners. They all could burn 4 dvds simultaneously in the same amount of time that it takes to burn 1. There was no performance hit for multiple discs. And they all had a single hard drive (sometimes IDE, sometimes SATA). So that's not the problem. This is the first time I am having this issue with speed.

 

Believe what you want.

IDE is different. The IDE optical drives run at data speeds such that an ATA-100 or ATA-133 can keep the pipe full.

A SATA HDD at full speed CANNOT saturate the data pipes of 4 SATA optical drives.
