Rather than plugging another FW or USB drive, I've been kicking around the idea of a network drive which would give me added capacity with 2+ drive bays, and not place such a burden on USB ports and USB expansion devices. Price is a big factor, so I'm not looking to spend tons on the enclosure. Might start out with one (1) 1.5 TB drive and add a similar drive down the road. I also need to include files created on both macs and PCs. Is this D-Link the way to go? Or would a Netgear ReadyNAS Duo be a better solution?
