WD My Cloud EX2 4 TB NAS
One thing to keep in mind with this home NAS is that if you're looking for a professional-light version which gives you a lot of tools for a home setup, then this option probably isn’t for you. This is a pretty simple model that comes with hard drives provided so there's little you need to do to set it up. It has a storage capacity of 4TB, though there are also diskless models available, along with ones that have more storage installed: 6TB, 8TB, or even 12TB.
What really allows this selection to shine is just how easy it is to set up since there's no need to install or swap out drives and you don't have to fiddle with a range of applications to get it up and running on your network. While it has 512MB of memory and a 1.2GHz processor, it’s not going to run as fast as something like the Synology DS715 so that’s something to keep in mind. You get a Gigabit Ethernet port and two USB 3.0 ports on this model which gives you some good connectivity, though it lacks an eSATA port.
