Burning Speed Optimization

[trenlong]

Hello,

I run a rafting company and we take photos of all of our rafting trips and deliver them via CD at our office. So I have to burn a lots of CDs really really really fast.

So here is what I am going to try to do:

I have a mac Pro dual 2.66 with 4 gb ram

I am going to use a sata PCIe card with port multiplication to control a 5 bay sata enclosure. In the enclosure I have 5 samsung dvd/cd burners (48x on CD)

and I am using roxio toast to burn. I basically copied the toast APP 7 times and will run each one with a corresponding CD burner.

What can I do to make it go at the full 48x?

I currently am running two burners in the internal optical drives but toast tells me they average about 3-5x so I was hoping to get a bit faster.

What can I do?

thanks,

tren

The only thing I can think of is more RAM. You might ask Mike at xlr8yourmac.com for advice or check with the folks at Otherworld Computing (www.macsales.com). Media quality also affects burn speed. LaCie makes a standalone 5-disc duplicator you might consider.

We take lots of pictures and sell lots of pictures.

on the weekend we take abouto 400 people a day and good chunk of them buy cds. So I go through about 50-100 cds a day on the weekend. We take a limited amount of pics, we just have a lot of people. I will bump up my ram I think its only at 4gb right now.

But it does work like a charm, I can burn 7 cds at a time with no problems, I am just tryinh to bump up the speed a bit.

Thanks for all the help,

I usually avoid burning at fast speeds.

 

I choose a slower speed for burn reliability.

 

In the past (burned with the iTunes software), in my experience, discs burned at high speeds don't last as long and degrade sooner.

Good advice, especially for audio CDs. The OP is trying to burn seven CDs concurrently to seven drives via seven open copies of Toast. While that works in theory, it may present some problems for how each copy of Toast is using the available RAM and how the Mac is managing the concurrent reading and transfer off all that data from the same file. I'd probably attempt this with multiple computers or a device that is designed for burning multiple CDs or DVDs. But I've never attempted this feat and don't have the knowledge to give confident advice.

Yes, that's a real tough one.

 

I'm a photographer and wonder how he would burn so many images.

 

I know wedding photographers who churn out 2000 images over a weekend, but...

 

Maybe he has lots of clients and wants to give everyone a disc with photos.

 

 

I think it's better to present fewer, well chosen images, than a mountain of unreviewed images.

 

The good one get buried, and you burn your poor computer silly.

 

 

I never present more than 40 images (that's the absolute maximum) to clients, as they will simply be overpowered by too many choices.
