It's no secret that the Xbox 360's disc drive is hella noisy, by far outstripping any incidental fan noises that might be going on inside that white box. Luckily, help is on the way -- sort of. Microsoft has started building its 360s with a new DVD drive manufactured by BenQ-LiteOn-Philips, the BenQ VAD6038, which purportedly runs "super-quiet" in comparison to the previous two drives used by MS, and even speeds up and smooths out load times. Of course, this does nothing for the 10 million plus current owners of Xbox 360s suffering from the noisy insanity of the older drives, but it does mean that as Microsoft ramps up production with this new drive, your next 360 hopefully won't fall victim to the whir.
