A single layer has only 1 layer that can hold data, whereas a dual layer DVD has 2 layers, so it holds more data than a single layer DVD.
To be precise, a single layer DVD holds 4,37 GB, and a dual layer DVD 7,95 GB.

The CD burning performance of current DVD drives is 40x (Plextor's drive does even 48x) which is almost identical to the 52x performance of CD burners. When looking at the numbers the CD burner seem to be faster, but the difference is negligible. You won't notice it.
You should know, you can't burn a complete CD at 52x. The inner part is written at 16x or 24x, and then in the middle part the burner speeds up to 32x and 40x, and only the outer part gets written at 48x or 52x, which results in negligible time differences. IMHO it's not worth it. Just get the LiteOn 832 and enjoy.

EDIT: "-" is the technology developed by Pioneer, and later the DVD+RW alliance introduced the technically superior "+" format.
Unfortunately "-" did not die, so we have both formats. But since all DVD burners can handle both it's nothing to worry about. Also, dual layer will first only be available with DVD+R.
