For the quietest and FASTEST Cd-rom, get the Kenwood 72X TrueX drive. It has a seven beam pickup which allows it to spin much slower than the average 52X CD-Rom, yet in all benchmarks it gets an average read spead of over 66X over the entire disk surface (most 52X cdroms rate in the low 40s) Truly an impressive dirve. You have to try it to believe it. A little pricy though around $130.00 Have seen them around 100.00 though. I have the 62X same drive but a little slower. I love it, never seen anything like it.
Good Luck
