Share the wealth: networked hard drives
As the per-megabyte cost of storage drops, hard drive makers have had to distinguish themselves in other ways. A logical move has been to add network capabilities to their drives, a move that's in line with the general proliferation of home and small-office networks. Multiple users can share data, music, and video files.
Keep in mind that there are variations among networked hard drives. Some incorporate print servers or FTP servers, while others include USB hubs that allow you to make a daisy chain of several drives for increased capacity.
