Super awesome device

By Paul Gregory on November 27, 2013

Size: Diskless Verified Purchase

I have been researching SAN devices for a while. This one looked like a great option. 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 repair the RAID, it just got stuck in some loop. I was able to migrate the VM back onto the esxi box. However I couls not repair the RAID. So... I just started over. turned off machine, popped out the drives, moved them to different slots so that the NAS would reformatt/ re partition the drives. It acknowledged the drives, showed them as 1TB each. Unlike the first time, it didn't 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 process of partitioning the drives, please 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's default displays. Like it has no idea what was going on. Obviously the web page control panel was attached, as it knew the status of the drives... and it is hosted on the ip address of the WD device.

I have turned the machine off and given up until after Thanksgiving. I used thee WD RED NAS drives. I am very hopeful that I am just overlooking something really easy, as the instructions are sparse and FAQ's are limited.

I am not dissapointed yet, as I think this machine will be awesome once I get it up and running.Read more ›

Unusably slow, process priority bugs, data not reliably accessible

By Mitch Bicquet on March 23, 2014

Size: 16 TB

I had high hopes for this product after installing 4 x 3Tb drives in Raid 5 and starting to transfer various 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 very unresponsive . After repeated attempts to login and load I realized that a wdphotodbmerger process was consuming 70-80% of cpu trying to generate thumbnails for images across all my time machine backups and various sources. I attempted to disable Media player support to no avail. file transfer speeds had crawled to a stall (<1mb/sec). I left the process 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 don't know why my changes got overwritten.
Another issue was trying to use the Web and FTP file transfer processes and automatic backups.
A major issue was when I popped one of the drives out to test the RAID rebuild before I would start removing files from my sources. The Auto rebuild starting right away rebuilding the RAID which took 22 days to complete You read that right - this was for approx 3Tb of data. I would have expected 8-12 hours at most. 22 days is a very long window during which any other failure would have meant the loss of all data. this was not with a fresh, 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 reduces the process priority or thumbnails, etc...) and got told that the product works as advertised. I cannot return it as I am past the 30 days.Read more ›

Excellent User Interface & Features but SLOW (UPDATED late December 2014)

By Stephanie Sullivan TOP 50 REVIEWERVINE VOICE on June 25, 2014

Size: 8 TB Vine Customer Review of Free Product ( What's this? )

As of the December 16th firmware V1.05.30 the Dropbox Sync app is back and performance seems 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've been using and installing several NAS servers lately, so I was excited to see what Western Digital had to offer with their "expert" EX4. I was both impressed and disappointed. It's well made, has a nice user interface but is slower than the competition. If you want more details on how it compares with the entry-level Buffalo LS420 and the professional Synology DS214 please read on.

The WD My Cloud EX4 8TB is a substantial piece of hardware. It comes with four 2TB WD NAS drives. I like these and in my prior testing the "NAS specific firmware" seems to make them a bit better in NAS applications than WD Black or even RE series drives. I've used them in Synology and FreeNAS based home-built devices with excellent results.

The EX4 unit itself weighs about 12 to 15 lbs with the drives installed.Read more ›

Worth having

Getting plenty of use. Interface a little clunky. Has taken a while to learn to navigate user, security settings. I would, and have recommended to friends.👍
