I did some searching in the forums to see if anyone is using this burning technique and turned up empty. So here it goes, you’ve got several burners of different makes and want to burn a bunch of discs with the same exact content. I have not tested this with a fast SSD drive so it will be interesting to see if someone wants to try and duplicate these results. Basically you need a PC with at least 8GB RAM (to handle a DVD image) less if you want to burn CD’s. RAMDisk software, I’m using GiliSoft RAMDisk, sells for $25, simple interface and works well. My PC tower can hold 3 burners, they are Pioneer 215L, Samsung 203N, and just recently acquired a Lite-On IHAS124 cross flashed to a 624. Open IMGburn and turn off all logging options, I also reduced the Buffer Size ( I/O ) tab down to 11MB. I didn’t do a lot of testing with the Buffer Size to see if there was a performance effect but everything ran well. Turning off logging reduces any unnecessary HDD writes potentially hurting performance.
So basically you start your RAMDisk, a size of 4800MB is plenty big for a SL DVD, copy and paste your DVD data over to the RAMDisk. Load your burners with blanks. Open three (or however many burners your using) instances of IMGburn, set your desired burn speeds and such. My old burners do well at 12X and complete close to 6 minutes, the new IHAS624 takes 7 minutes at 12x so I’m using 16x and now all three burners complete at the same time (within a couple seconds). After the RAMDisk is finished copying files onto it your ready to select the data you want to burn from the RAMDisks in IMGburn. Go ahead and start each instance of IMGburn and watch the buffers stay rock solid at 100%.
Most of us don’t need a DVD duplicator for those rare times we need to burn multiple discs nor do we want to invest in a device that is inferior to our modern PC’s. Also note it should be possible to install IMGburn on the RAMDisk, this may reduce HDD access even more while burning, the RAMDisk software then has the option to save whatever data is on your RAMDisk for future use in a image file.
I’m a little disappointed with the LiteOn performance but hopefully its learning
