Seagate’s giving its FreeAgent Go drives a new 640GB capacity. It may not be the first external to cross the 500GB threshold, but it’s certainly one of the slimmer ones, physically. Other than that, there’s nothing too special here.

It’s still the standard USB-connected with up to 480Mbps transfer with multiple color options. We don’t have any info on pricing or availability, but since Seagate’s posting promotional materials on its main site, it won’t be long.
