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.

What about ventilation and temperatures? Does it have a fan?ganeshts - Friday, October 9, 2015 - link
Yes, it does have a fan that is audible ONLY at startup. Beyond that, during operation even with a WD Re drive (which is a power guzzler compared to the WD Red drives that the units actually ship with), the fan was very quiet - not audible at the noise levels in a usual room.As for ventilation, you can see from the product chassis photos gallery - there are plenty of perforations around the top and rear - the chassis design is the same as the other 2-bay products from WD over the last two years - it has remained that way partly because it has been very effective in terms of keeping optimal operating conditions for the internal drives.

Hi Ganesh,Can you please include idle power (with disks) in your NAS/SAN reviews?
Thanks!

Yes! Please! For something like a NAS that is expected to be on 24x7, idle power usage is far more important than RAID rebuild.clok1966 - Friday, October 9, 2015 - link
While i have not used this model, I have tired to use 2 other solutions from WD older models where called WORLD BOOK. Both failed in warranty period (reason I have 2, 3 actually but I wont be using the 3rd) and I will no longer use them. Warranty was easy, but all data was lost. Online are some sites on recovering data (both times it was not the HD's but he hardware running it that Failed) but you need to take apart and have linix box, which voids warranty. I have used other products with the same idea from other manufactures and had no fails. Just bad luck? not sure, but 2 fails is to much in a short time when using them as backups.edward1987 - Friday, October 9, 2015 - link
Here it says Operating temperatures 41° F to 95° F,do not really need a fan.

Another question: can two of these be on the same home network? I already have sad experience with a Seagate home NAS unit which allowed only one on a network.Any other comments on my use case appreciated: I'm not after speed nor size, mainly, but it's vital that that no single hardware failure can result in a loss of data. I would use two of these NAS boxes to get that independence. And probably JBOD within each one for the same reason. Feasible?

I believe there is nothing technically preventing two of these devices on the same network. Just make sure they are not both being setup simultaneously as the default name of the device is 'WDMyCloudMirror' and some routers can get confused when two different devices with different DHCP IP addresses have the same device name. It is possible to change the name of the device in the Network Settings section from the web management interface.If speed / size is not a constraint, and you don't want single hardware failure resulting in data loss, yes, your solution will work - I might advise going with RAID-1 within each NAS, as that will allow automatic rebuild if one of the disks fail. You will still have the other NAS obviously, but the amount of time you spend with the data not having any protection at all is reduced quite a bit with the RAID-1 configuration.

Can you use this to sync/backup folders over the internet? I didn't see anywhere mentioned if this only works on lan. I thinking of using this as remote back up. Install the software on one pc to back up a folder and it will then transfer that over the internet to the device at another location.ganeshts - Friday, October 9, 2015 - link
Yes, it is available over WAN also.Details on the necessary configuration: http://support.wdc.com/KnowledgeBase/answer.aspx?I...
