I just finished ripping 600 cds to my computer using a Samsung SE-208AB/TSBS external drive. It has solid C2 error correction, which is key for getting secure rips. Runs quiet and has never given me any problems.
Only drawback is that it might require two USB 2.0 ports, depending on the power supplied by the USB ports in your computer. I only needed one, though, as I had it connected to a USB 3.0 port.
Best part is that it only costs $35!
