Best network attached storage(Updated December 20, 2013 1:55 AM PST)
If you have multiple computers on your network, you're a candidate for a network-attached storage (NAS) device. Some NAS servers simply act as a shared volume for backing up and sharing files across your network, while others can do a lot more, such as sharing a printer among your networked PCs, acting as a media streamer or even a surveillance system by supporting IP cameras. You'll find NAS devices with a single drive and those with multiple drives that allow for greater data protection and higher capacities.
Here's a list of the current top NAS servers.
The Synology DiskStation DS1513+ is easily one of the best multiple-bay NAS servers to date, performing superbly both as an advanced storage server and as the central host for a long list of home entertainment and business uses.
The DiskStation DS712+ is one of the best dual-bay NAS servers on the market, for both home and office environments. It's also one of the few that offer storage scalability for those who want to start small and add more capacity later.
