I'm looking into getting a 750GB external disk with Time Machine coming soon. I've narrowed down the choice to the Lacie Quadra 750GB and the Western Digitial MyBook Pro 750GB. Both offer FW800. The Lacie is about 10% more expensive than the WD but also offers a 2 year warranty as opposed to the 1 year of the WD. What should I get? The one thing that bothers me with the Lacie is that you don't know what disk you're getting. I've had a Lacie Porsche for about 3 years now with works great still, so no bad experiences (yet). Any experience with respect to noise levels and reliability on either drives?
