I've been using this little guy to backup my laptop as well as a near-line storage device, and it works great, no problems at all. It has USB & Firewire ports, but I only have USB on my laptop. I really like it's quietness, if it weren't for the lights on the front I'd never know if it were on or not... no fans either, and it doesn't get too warm, but I've got it on a shelf with a lot of ventilation. And for my needs it's more than fast enough... I don't think I'd use it for video editing, but for file access it seems as quick as my laptop's drive. How much do I like it? I'm considering buying another!
