I know there's not really a "best," necessarily, but I'm topping out as my photos have filled up my 80 gig external drive (Smart drive). I'm thinking in the area of 250 to 500 gigs. I almost bought a My Book at a good price, but CNET says they are slow. In fact, CNET says that about a lot of the external hard drives, including most of the Western Digitals. I tend to respect Cnet, as they've steered me right in the past. Can't really use the Firewire option, so I'm just looking for a good buy on a reliable drive. Any opinions?
