I picked up a Cendyne 40x12x48 CDRW (Liteon rebadge) and I currently have a Plextor 12x10x32a. Which would be a better CDRW to buy for burning audio cds, and buring backup of files on my PC. I know the Cendyne is much faster, but doesn't the Plextor let me burn protected audio cds or something like that?
