The WD My Cloud 3 TB is an excellent option if you are looking for an affordable, feature-rich NAS for home or small office use.
It is simple to install and configure, which is an excellent characteristic for this kind of product. It can be accessed from outside your local network through the internet, and can be used as a media streaming server for multimedia devices in hour house, which is also excellent. And its price is fair, considering it is even cheaper than an external hard disk drive of the same capacity.
The performance is good for a network drive, if used under optimal settings, i.e., with cabled network with Gigabit Ethernet router and Gigabit Ethernet interface on your PC. Our tests also showed that, if you use an entry-level Wi-Fi connection instead, the performance degrades dramatically.
We can also conclude that a USB 3.0 external hard disk drive is still a better choice if you only intend to acess the storage by a single computer, as a backup unit, for example; USB 3.0 drives are faster.
It could also have come with Wi-Fi capability, but we understand that this would dramatically increase its final price.
