A proprietary technology by Plextor. This technology uses system memory to buffer information before recording it onto a CD. So far, Plextor is using it on their newer 12x10x32 IDE CD-R's. This technology was developed to somewhat lower the number of coasters put out by your friendly neighborhood Napster pimp. And also to try to rival the advantages of SCSI over IDE when it comes to burning.

Look Ma!, I can record a CD and node at the same time!
