Multi-Client Performance - CIFS
We put the EX2 through some IOMeter tests with a CIFS share being accessed from up to 25 VMs simultaneously. The following four graphs show the total available bandwidth and the average response time while being subject to different types of workloads through IOMeter. IOMeter also reports various other metrics of interest such as maximum response time, read and write IOPS, separate read and write bandwidth figures etc. Readers interested in the actual values can refer to our evaluation metrics table available here.
Note that the scales on the graphs are different for different NAS units. As mentioned before (and evident from the maximum response times in the linked results), the unit fared quite poorly with respect to simultaneous access as the number of clients increased above 10. Though we were able to complete the tests, the performance was not consistent.
We have provided data from the evaluation of four different 2-bay NAS units above. The closest in terms of hardware platform is the ioSafe N2 (the Synology DS213), and it is readily evident that the N2 manages to outperform the EX2 in almost all scenarios while exhibiting better consistency too.

The article states: "The Western Digital My Cloud EX2 is bundled with a 36 W(12V @ 3A) adapter. A power cord (customized to the country of sale) and a network cable are included in the package." The EX2 units do not include a power cord. The 36 watt power adapter is a fixed-plug wallwart-style unit. The comment about a power cord seems to be left-over from the EX4 review.ganeshts - Tuesday, March 4, 2014 - link
Thanks for the note. I have fixed the relevant text.redmist77 - Wednesday, March 5, 2014 - link

Well, that just kills my idea for "Cloud-soft" (tm pending) toilet paper!futbol4me - Thursday, March 6, 2014 - link
One very useful non-geeky benchmark would be time machine backup performance. I have a mybook live and while it may read and write files with decent performance via afs or smb, time machine backups are almost unuseably slow.teich50 - Saturday, March 8, 2014 - link
Has anyone figured out how to perform an encrypted Time Machine backup to My Cloud? I think, by default, the Time Machine back up writes to the Guest account with no encryption, which is scary.Atty - Sunday, March 9, 2014 - link
What is your recommendation on hard drive choice? For this to be used to share and store mainly media files and stream them to various devices. Would it be worth the investment to get the re4 drives or are the red drives suitable?Cybernut1 - Friday, March 21, 2014 - link
Red drives are recommended.For a home or small office setup Re drives are overkill. Re drivesare geared towards data centers. WD recommends Red for most common uses for this product though they will support select few other drives. Here's the full list of supported drives - http://www.wdc.com/en/products/products.aspx?id=11...Cybernut1 - Friday, March 21, 2014 - link
The couple big issues for me with this having used it for a week are:1) Currently the ftp functionality is broken (if you are trying to ftp from outside your local network - which is almost 100% of the time). Broken because you cannot save your external IP for passive ftp to work and that is critical. It keeps resetting the external IP value to 0.0.0.0. I have a trouble ticket open with their tech support but ETA for fix is unknown at this time.
2) There does not seem to be any way for sftp - which is really a reason for many to get this. Even if you can get ftp to work (by going into the shell and making unsanctioned edit to the ftp configuration file), you cannot really do much about sftp. I am used to creating sftp via shell access for work - but here when you try to create an user in the embedded lightweight linux, that user cannot login to the shell no matter what privs you give that user. And without a remote way to ssh into the box, you can't do scp or sftp. So their marketing claim about "Secure FTP support" on this page -> http://www.wdc.com/en/products/products.aspx?id=11... (click on Advanced Serving tab) is rubbish.

I found WD My Clound EX2 and was happy because I bought this was a great idea and a perfect solution. I found the product has several problems that makes this product useless. The problem is the following. The unit CPU work 24/7 at 100% because it has issues with a process name "Convert" that tries to create thumbs to media files. The problem I´m experimenting it not an isolated case, you can find in WD Community lots of people having the same problem. WD is aware of the problem for a while and has not find a solution (firmware update) or doesn´t care.This problem:
- Not been able to access the unit.
- When you have access the unit crashes.
- Difficulty to access files.
- Continually crashes and need to be restart.
WD should stop selling My Clound EX2 and start a refund process.
