Burning simultaneously with blu ray possible?

Postby ninus3d on Mon Nov 12, 2007 12:13 pm

Can I burn an image (the same image) on 4 blu ray drives at once?
And what would be required of me to do so (both hardware and software)

I work at a QA office and we get a new build of the games we work on
around every 2nd day, we then need this build distributed to around 20 consoles so alot of time is wasting because we dont have a good solution
at the moment! Any help would be incredibly awesome ;)

You could do this a couple of ways. The first way, you could get four internal or external Blu-ray drives and hook them up to your computer. Nero used to be able to write to multiple drives at a time but I'm not sure if it can do that with Blu-ray and/or four drives. Anyone know?

Since you're going to be doing this often, your other option would be to buy a Blu-ray duplicator. You can buy a tower with 2, 4 or more drives in it. The cheaper ones hook up to your computer via USB and use software installed on it. Otherwise there are standalone units with built in hard drives.

Thanks for the reply Ian :)
For some strange reasons, even more so since we have one for dvd
already, they dont want to buy one for BluRay.

It will most likely be 4 internal drives but my main concern is how i spread
the datastreams around. How much data does a steady burning of a
BR disc need? Can I run 2 drives on 1 controller or do I need as much
as 4 individual S-ATA controllers (including the one on the motherboard)
OR are there some fancy way to send the stream to all burners, since
its the same data?

I will love every one of you who even give me a hint here ;)

When writing at 2x, the transfer rate is at 72Mbps. Serial ATA can more than handle this. Unless there is some limitation I don't know about, you should be able to use the same controller and put a drive on each port.

The biggest limiation will probably be the hard drive where you have the image stored. Even then, most drives should be able to handle the demands of four Blu-ray drives writting at 2x as the transfer rate would be only 288Mbps (36MB/s).

Stick with Panasonic BD-R drives, they produce much better burn quality results with most media. If you end up with LG drives, don't burn at full speed, or your consoles will have problems reading the latter part of the discs.

I did some research into this when helping another game firm pick out a BD-R tower :)

And really, I HIGHLY recommend re-evaluating getting a dedicated tower. It's a little more money in the beginning, but it's less work and frustration on going... and computer systems have so many better uses then just being tied up with burning discs day in and day out.
