Seagate is expanding its GoFlex family of 'upgradeable' external HDDs with a new product that will provide networked storage and media playing capabilities for home computer users. The It may lack some of the features of more advanced NAS solutions, and the fact that it is a single drive product means there's no mirroring-based data protection against crashes. But Seagate is hoping to lure buyers with ease of use and competitive prices. The GoFlex Home is pretty much plug-and-play and will run you $160 for the 1TB version or $230 for the 2TB model.
