Could a LIVE update really quiet the 360's noisy drive?

Gamepro.com is claiming from a source of theirs that a simple update over LIVE could quiet the XBOX 360's drive noise.

 

It appears that even early Xbox owners might be able to hear the benefit of a quieter drive. Kotaku has pointed us towards a German site named Cynamite, which claims that a recent software update for the Xbox 360 significantly decreases the noise emanating from the console's disk drive. The site states that the update only applies to debug machines used by German journalists, but assumes that it could very easily be applied to conventional Xbox 360 units.

The article reports that the update gives the console more control over the speed of the drive by allowing it the option to run more slowly. Without the update, the drive is conditioned to run at either full speed or not at all, but never a speed in-between. Although no technical experts were available to verify the veracity of the site's claim, they did quote Microsoft Platform Manager Boris Schneider-Johne, who claimed at Games Convention 2006 that Microsoft was working on controlling the speed of the drive.

However, the site also brings up the possibility that slower drive speeds could lead to longer loading times. Or, as Google's translation service put it, "the load times could extend with plays by the software update something."
