Hiya guys. I was going to get a WD MyBook with FireWire 800, but this deal looks good. Amazon have the external drive mentioned in the title for £99.99. Just a couple questions before I bring out the plastic: 1. Does anyone know how quiet it is, and how hot it runs? 2. I assume it will be perfect for Time Machine - It's 750GB and I have a 320GB HDD in my iMac. 3. Is it a good price? Thanks very much!
