Network-attached-storage drives make it easy to back up your data and share files across your network. Which of these eight models is the right repository for your data? Network-attached storage (NAS) is a scary name for a surprisingly simple technology. Take a standard hard drive like the one inside your PC, slip it into a small enclosure that has an Ethernet port, connect it to your router, and you have a NAS drive. Within minutes, the drive should show up on your home network, allowing friends or family to easily share files, stream media from one PC to another, and back up data to the same drive. Some NAS drives are accessible from any computer connected to the Internet, giving you the option to share photos and access files when you're on the road.
