Smartwrite
"A technology called SmartWrite manages the stream of data being recorded, apparently preventing underruns even when you are using your computer for other tasks. Just the same, I recommend not running tasks that hog your resources, such as saving, printing or otherwise processing huge files"
This technology has existed since 12x CD-RW drives first came on the market, it's been standard on every drive produced since then. Without it even 16x CD writing would be massively unreliable.
