"Western Digital introduced its NetCenter network hard drives for small office and home users. NetCenter network drives are the newest addition to the WD Essential external hard drive product family. In just three simple steps, WD's NetCenter network hard drives make it easy to share and save digital pictures, video and MP3 files, and printers across small office and home networks using a wired or wireless router. Users simply plug in WD's NetCenter network drive, run the installation wizard and use WD's EasyLink utility to set up the NetCenter network drive as a local drive on any PC or MacintoshR computer on the network." Just about evey hard drive maker has released a version of these "network" drives that allow you to share and back up your data across your home network. Personally I've been watching them with great interest and I'm thinking I might pull the trigger on one here soon. 320GB sounds about right. 8)
