Hi! I'm getting the Airport Extreme Base Station and could use some tips on choosing a USB drive to go with it. So, any experiences with any of the following drives: - Buffalo DriveStation 500GB SATA - Iomega Minimax 500GB - LaCie Hard Drive Design by F.A. Porsche 500GB - LaCie mini Hard Drive & Hub 500GB - Maxtor OneTouch III - 500GB - Western Digital MyBook 500GB Do they work well with AEBS? Do they spin down when not in use? Are they noisy? Any other drives I should be looking into?
