Recent reviews:

I have been researching SAN devices for a while. This one looked like a great choice. I loaded (3) 1TB WD RED NAS drives into this and powered it on. It formatted the drives ( default RAID 5 ) and I had 1. 9TB of space. So far so good. I set up iSCSI with 1TB of the RAID 5 volume. Worked great. I Migrated a virtual machine from local storage on my esxi 5. 1 box over to the iSCSI drive. Worked wonderfully. Went to bed. In the Morning the device informed me that the RAID was degraded. :(I attempted to use the control panel to fix the RAID, it just got stuck in some loop. I was able to migrate the VM back onto the esxi box. But I couls not fix the RAID. So.. I just started over. Turned off machine, popped out the drives, moved them to different slots so that the NAS could reformatt/ re partition the drives. It acknowledged the drives, showed them as 1TB each. Unlike the 1st time, it did not automagically start formatting. So I followed the directions online and changed the RAID to RAID 5. The web page control panel said it was in the procedure of partitioning the drives, be patient. I was patient all night long, woke up in morning the page was stuck again. The LCD on front was just in it is default displays. Like it has no idea what was going on. Clearly the web page control panel was attached, as it knew the position of the drives.. And it’s hosted on the ip address of the WD device. I have turned the machine off and given up till after Thanksgiving. I used thee WD RED NAS drives. I’m hopeful that I’m just overlooking something really easy, as the information are sparse and FAQ’s are restricted. I’m not dissapointed still, as I think this machine will be awesome once I get it up and running.

As of the December 16th firmware V1. 05. 30 the Dropbox Sync app is back and performance looks to have returned to pre-Aug update speeds (about 30MB/s in my testing for writing). This update took a long time to install on my EX4 after a reboot – FYI. More detail on this update at the end of this review. Read on.. As of the Aug 21, 2014 firmware V1. 04. 05 the same copy test I used in the initial review slowed by 2/3 from 30+MBs to 10MBs Detail in the updates at the end. Read on.. The original review is below. Update detail at the end. I have been using and installing some number of NAS servers recently, so I was excited to see what Western Digital had to offer with their “expert” EX4. I was both impressed and disappointed. It is well made, has a nice user interface but is slower than the competition. If you want to have more details on how it compares with the entry-level Buffalo LS420 and the professional Synology DS214 read on. The WD My Cloud EX4 8TB is a considerable part of hardware. It comes with four 2TB WD NAS drives. I like these and in my previous testing the “NAS particular firmware” looks to make them a bit better in NAS applications than WD Black or RE series drives. I have used them in Synology and FreeNAS established home-built devices with excellent results. The EX4 unit itself weighs about 12 to 15 lbs with the drives installed.

I had high hopes for this product after installing 4 x 3Tb drives in Raid 5 and starting to move different files and backups that I kept on 4-5 external USB drives and Time machine backups. After just a week of use and filling approx 3 TB of data I noticed the web admin interface was unresponsive. After repeated tries to login and load I realized that a wdphotodbmerger procedure was consuming 70-80% of cpu trying to produce thumbnails for pictures across all my time machine backups and different resources. I attempted to disable Media player support to no avail. File move speeds had crawled to a stall (<1mb/sec). I left the procedure run for 3 days with no luck and had to create an ssh account to login and remove execute permissions on these non essential processes to recover access to my files. This is an operation I have had to do twice more – I do not know why my changes got overwritten. Another issue was trying to use the Web and FTP file move processes and auto backups. A big issue was when I popped one of the drives out to test the RAID rebuild before I could start removing files from my resources. The Auto rebuild starting now rebuilding the RAID which took 22 days to finish You read that right – this was for approx 3Tb of data. I could have projected 8-12 hours at most. 22 days is a long window throughout which any other failure could have meant the loss of all data. This wasn’t with a new, blank drive but from one of the 4 live drives. I have contacted WD support about these, asking for some explicit solutions (firmware update that decreases the procedure priority or thumbnails, etc.. ) and got told that the product works as advertised. I can not return it as I’m past the 30 days.
