Best network attached storage(Updated May 15, 2013 2:55 AM PDT)
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 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.
The DiskStation DS1511+ is arguably the best five-bay NAS server on the market for both home and office environments. Novice and home users, however, might be intimidated by its setup software and the number of features it has to offer.
The Disk Station DS410 is one of the most affordable four-bay full-feature NAS servers on the market. While it's overwhelming for novice home users, advanced users will also find it to be one of the best RAID 5-capable NAS servers for their home or small business environments.
