When my G5's crappy DVD drive died, I replaced it with a Pioneer DVR-111D. I got my Mac Pro and the thing imported CDs and DVDs slower than my G5! I just stuck this $35 111D in my Mac Pro and WHOA! CDs rip at 40x! (320KBp/s Mp3, with error correction). The Mac Pro comes with an NEC drive re-branded as a Sony. The NEC Firmware update (someone repost it, pls) speeds up the Sony but caused stability issues so the best thing to do seems to get a new drive like the 111D. Oh, and it's dead quiet. I love NEC but they make CHEAP stuff, this stock drive sounds like a lawnmower and it's slow as hell. I'll probably only use it when I have to burn 2 things at once now.
