Single Client Performance - CIFS on Windows
The single client CIFS and iSCSI performance of the WD My Cloud Mirror Gen 2 was evaluated on the Windows platforms using Intel NASPT and our standard robocopy benchmark. This was run from one of the virtual machines in our NAS testbed. All data for the robocopy benchmark on the client side was put in a RAM disk (created using OSFMount) to ensure that the client's storage system shortcomings wouldn't affect the benchmark results.
The benchmark results suggest that the My Cloud Mirror Gen 2 actually leads the pack in most of the read workloads. For writes, it is still in the top half of the pack.
These results are actually a pleasant surprise for a unit that targets home consumers. Obviously, the platform is very powerful, and the home consumer focus has been brought into play by disabling certain features in the firmware. Due to that reason, we do not have the corresponding NASPT benchmark results for iSCSI LUNs.

My concern about these consumer devices (and other consumer Cloud backup solutions) is how will the ISPs respond to having several thousand GB of data being constantly uploaded by each customer? On most my machines I try to avoid having my OS files uploaded to a Cloud service, but I wonder how many people do that. Someone could probably set one of these up in a manner where it would be uploading files 24/7.stephenbrooks - Sunday, October 11, 2015 - link
I imagine these are differential backups, so only modified files get transferred, based on comparison of file lists and modified dates (only a few MB for the whole disk).Also ISPs already have a bunch of BitTorrent people who upload constantly and they seem to cope with that (sometimes they get throttled).

I don't think this is copying anything to WD's servers, except when you use remote access, then it downloads on-demand to the remote device, possibly via WD's network.Conficio - Saturday, October 10, 2015 - link
Really no IPv6 support? Is this 1999 or what? It's linux underneath, so one has to deliberately disable IPv6.ganeshts - Saturday, October 10, 2015 - link
It is all part of a differentiation drive when compared to the EX2 series.I suspect most of the consumers who are going to buy this unit probably don't even know what IPv6 is.

I've used two older WD EX2100 units (12TB) and have found WD's configuration interface to be the easiest to use of any NAS I have ever worked with. I think my grandma could set one up.Their software developers and UI designers deserve a medal.

What SSH client is that?Moishe - Wednesday, November 4, 2015 - link
Thanks for mentioning the lack of features in this versus the EX2. Lack of encryption in this is a deal killer.mikato - Saturday, November 14, 2015 - link
I don't think you said anywhere in the article that this 4TB model comes with 2 x 2TB drives! I had to look at the photos to see that. You list "USD 310 (2x 2TB)" for the price entry in the specs table, but that doesn't say anything about which model it is for (I see it's the 4TB one). If set up as a mirror, as by default, and as the product is named, you only get 2TB or storage. They sell this as having capacity of 4TB. WD's website gives you no hint about this. I looked up the listing on Amazon and thank goodness they do have "4 TB 2X2TB" in the technical details, but otherwise there is no hint there either - actually when you choose the model at the top it says "Capacity" next to the 4TB which actually only gives you 2TB capacity.
