Performance - more
For the File Copy Write test, the results were completely different. Not only did My Cloud top the charts at 50.6 MB/s, it bested its My Book Live sibling by 15%.
WD My Cloud File Copy Write Performance
As noted in the Buffalo TS3400 review, we have switched to classless ranking for NASes. Shown below is the Ranker Performance summary for the WD My Cloud. Note that this ranking is for all products tested and doesn't relate to a particular class of processor or number of drives.
For the Total NAS ranking as well as for write benchmarks, it ranked #54 out of a total of 67 products tested. Relatively low read scores undoubtedly dragged down the overall ranking. And, bear in mind, that its price is on the low end of the NAS spectrum.
WD My Cloud NAS Ranking
If you filter the NAS ranker for single drive devices, you'll see that the My Cloud ranks fifth out of eleven. It is just narrowly edged out by the #4 ranked WD My Book Live that it replaces. The top three ranked single-drive NASes are BYOD QNAP devices, which, with the additional cost of a 2 TB drive added, would make them significantly more expensive than the My Cloud.

WD is in the process of phasing out WD2go. But WD2go users can update to the free My Cloud app. The good news is that the My Cloud app is backward-compatible with My Book Live and older products. WD2go isn't completely gone, however. When you go to www.WDMyCloud.com, you currently get redirected to the WD2go site. I imagine that will be changing soon.
Behind the scenes, Western Digital has completely redesigned the architecture of the base operating system and the cloud service. They claim that the new architecture allows for faster response to queries from the mobile apps including delivering thumbnails for photos and music artwork. Indeed, in my remote testing of the My Cloud NAS, responses were surprisingly quick.
The newly designed interface is certainly an improvement from the older UI found on the My Book Duo Live. As with its predecessor, setup is extremely easy. The upgrade of the DLNA media server to Twonky Version 7 made for a great experience on my DLNA streamer. Most importantly, WD has taken all of the hard work out of remote access with an architecture that works even if UPnP has been disabled on your router or if you have multiple levels of NAT. The latter will be welcome news to folks who have a combination modem / router that can't be set to bridge mode.
My only real complaint is with browser-based access. I spent far more time installing/uninstalling/reinstalling Java on multiple platforms and activating plug-ins in multiple browsers than I did setting up the My Cloud NAS. If only there were a way to provide browser-based access without using Java, I could have finished this review much more quickly.
With a list price of $149.99 for the 2 TB flavor, Western Digitial is, as usual, very aggressive on pricing. If you're looking for a single-drive NAS with great remote access features, My Cloud is hard to beat.
