Also depends on how fast your cd-rw is. Most likely the dvd-rw you purchase will be a cd burner also but, only 16x or 24x. Depending on the one you get. I have 4 drives on my system now. A first gen panasonic dvd-ram, plextor 16x and 40x, and a lite-on 52x. I just ordered my pioneer dvr-105 and a dvd-rom last week. When they arrive i'm going to swap out the 16x plextor because the dvd-rw can burn at 16x and the dvd-ram because I just use it to rip anyway.
