Hi all, I'm considering purchasing an 80GB hard drive from New Egg. I've narrowed it down to to drives that are the same brand. I don't know much about external hard drives but these two have good reviews. They're the Western digitial Essential HD or the Western Digital Dual Option. They're within a few bucks of eachother. I like the hot swap of the essential, however the timed backup of the Dual Option is nice as well. Any pros/cons either way? Here's the link to the website. They're the first two products shown when you scroll down: http://www.newegg.com/Product/Produ...14+1035307792+4027&Submit=ENE&SubCategory=414 I'd appreciate any input, thanks.
