Hardware is fine, supportig software is unreliable.

Reviewed in the United States on November 18, 2017

Size: DisklessVerified Purchase

* Update 01/11/2018 * I'm officially giving up on this NAS and will be replacing it with another one from a different manufacturer. Syncing now never works outside of my home network. I also can't access the dashboard anymore even when I'm connected to my home network. Using this device has been nothing but 7 months of inconsistent performance and frustrating software issues that seem to have no resolution. Don't be fooled by Western Digital's answer to this review - it did absolutely nothing to help. Only thing left for me to do now is decide whether I'd want to attempt to sell this thing off (dunno that I could in good conscience) or burn it.

* Original Review*

Five months of use and I'm still running into the same recurring problems with the WD Sync software. It'll stop syncing intermittently, showing a "No internet connection detected" message while my computer clearly has internet access. When it's not that it hangs at "Signing in to MyCloudEX2Ultra" or it reports that the device is missing. I've tried rebooting the device, adjusting settings within the Dashboard, adjusting settings on the router, adjusting firewall/malware settings on my computer and uninstalling and reinstalling the WD Sync software numerous times - nothing works. A firmware update didn't help, either. The software just appears to be extremely temperamental and unpredictable. When it does work, it's great, and automatically syncs and backs up files between my desktop and laptop as expected. Unfortunately, however, I'm frequently forced to use the My Cloud web interface to manually upload or retrieve files. At least I can say that the hardware has been reliable and I haven't experienced any data corruption or loss like other users have reported. Still, this system isn't exactly working as expected and the software issues are really frustrating. I'm aware that numerous other users have reported similar problems but, unfortunately, it appears that the support Western Digital offers is severely lacking, and user-run support forums are confusing, irrelevant or lead to dead-ends.

Unreliable. DON'T BUY

Reviewed in the United States on January 15, 2019

Size: 8TBVerified Purchase

I'm shocked that these WD cloud devices are rated so high by so many sites. I did a lot of research before buying this WD Ultra EX2. I was tenative about buying because I had a 1 TB device from them about 8-9 years ago and hated the interface and sluggishness of its backup. I bought a Seagate 4TB about 2 years ago that has been great but was now ready to have a wifi cloud in the home to keep on top of all the photos/videos and work stuff that I want to ensure I don't lose. After months of trying to get this to do what it's supposed to do with my Macbook pro, and iPhones, I can strongly say that this device is unreliable and pure JUNK. It never backups everything wether handled manually or through their auto backup process with the phones. Tons of stuff is always skipped over and missed. How can I trust this to back anything up!?! It's painful to know I wasted $400. Thinking I'd eventually get it worked out. I finally decided to contact WD to get a refund but I doubt they will. They'll blame me, my internet connection, or amazon. DO NOT BUY THIS!

Ugh, wish it would work

Reviewed in the United States on October 15, 2019

Size: 8TBVerified Purchase

I really wanted to like this, but it just doesn't work well. Before I purchased it I called WD and talked to a very friendly tech to make sure it could do what I was looking for, which is to remotely back up my laptop as I travel whenever I connect to the internet. He assured me that if I bought this model and used one of their programs (WD Sync) that it would. When it arrived I was having some trouble so I replied to the last email from the tech and he called me a few hours later. We spent over two hours on the phone trying to get it set up, but their software is full of bugs. It crashes and won't reopen, forcing me to uninstall and reinstall it four times. The tech was very helpful, took his time with me, but we could never get it to work. I have no idea how well the hardware works because we could never get it setup properly. It's going back tomorrow.

Great until it fails

Reviewed in the United States on October 4, 2020

Size: 16TBVerified Purchase

I bought one of these (16TB version) a few years ago and everything had been working fine.

I had RAID turned off because I wanted to actually get 16TB of capacity, not 8. Recently I just received a message that one of the drives was failing the self-check. So I immediately turned the NAS off and ordered a replacement drive. Well here's where it gets fun. I have a new drive, and can put it in the port, but I have no way to recover the old data from the old drive onto the new drive.

What's more - the NAS creates a shared volume across both drives so now that the old drive has been swapped out, I have no way of accessing the data that was on the good drive either. Effectively, there's no data transfer or recovery tools available. And if you contact WD (which I did) they sent me a link to a guide telling you how to insert a new drive. I explained that I am capable of inserting the new drive, but I want to still have the 16TB of data that was on my device - not just reformat the whole thing and start over. I was told I needed to contact some third-party data recovery company and pay for that service because they don't support data transfer/recovery and couldn't/wouldn't help me.

So in the end, I now have potentially lost 16TB of data and WD is 100% useless. There is no way I will ever buy another product from them with that level of "support".

Read carefully - this is probably NOT what you think

Reviewed in the United States on June 19, 2021

Size: 4TBVerified Purchase

I’m gonna keep this short. Believe the one star reviews, friends. This product 100% does not work the way you expect.
Pro: easy to set up. Works ok.
Cons: uses a proprietary interface which really, really sucks. There isn’t an alternative and you cannot access this from multiple devices on your home network like a shared drive or nas. Everything goes over the internet, to the WD drive, back over the internet to whatever device you use to access the data. You cannot link to the data directly. You are trapped in that interface. Think that over. Read up before you buy.

Will never buy a WD product in my life again

Reviewed in Canada on December 27, 2019

Size: DisklessVerified Purchase

Pros: none
Cons: crappy proprietary software, slow to wake up, admin UI is so bad that most ppl (including myself) opt for SSH into the server directly

I put in 8TB of WD's own NAS grade hard drives and ran a RAID 1 setup. After a year of very minor use of only backing up pictures and documents, this piece of crap started to max out CPU at 100% from God knows what. Cannot access the UI - opening up the login page takes 10 min, another 10 min to login then it just dies. I guess I'll just switch to cloud based storage options and never buy another WD product in my life again.

Great External Hard Storage, Terrible Network Storage

Reviewed in Canada on March 30, 2021

Size: 4TBVerified Purchase

If I just want to review this as a external storage hard, I would probably assign 4-5 stars for this.
But the philosophy of this product to me, is accessing to your cloud network remotely and use the benefits of this personal HDD.

I uploaded some of my personal files which need to access it remotely and also tried to set a hierarchy for this, spent hours to categorize layer and tried to link with my phone as backup storage of my pictures.
My experience for this was disaster , I just wasted all my times and money for this.
This is some bullet major issues:

- This device is offline most of the time. so you need to physically restart it and wait for 15-20 minutes to rebooted.
- 4 of 5 tries to remotely connect to this Failed. ( Error : Your device is offline! )
- Long time process of restarting ( 15-20 minutes)
- Backup folders and layers were not managed properly and most of the time will be restored to the first
settings.
- Layers/ Hierarchies will be replaced to the default settings.
- Not a routine software update from support team to fix the issues
- No active customer support for share and fix all this issues.

(Update after 1 year use: My issue to access this device and process time getting worse and worse and worse )

Excellent NAS with cloud storage

Reviewed in Canada on November 12, 2020

Size: 8TBVerified Purchase

This NAS offers SMB for Windows devices and optionally NFS for Unix type operating systems such as Linux and MacOSX. It also maintains a contact with Western Digital's website where you can create a login and access your files through there. Apps are provided for both Android and iOS and it can synchronize your DropBox content to it. You can set up shares to do Windows backups to but the shares has to be publicly accessible to all users as the Windows backup just synchronizes files to the share hence all users on the Windows computer has to have write access, this is really a limitation of how Windows does backups. This may be a problem for small businesses as it means all files are accessible to everyone which honestly is a common problem with any office using Windows. This is the older version of Western Digital's MyCloud devices so they actually have two different MyCloud accounts you can create, this caused some confusion initially and the documentation is ridiculously obtuse. Still, you can back up all your computers, all your phones, upload all your photos, store all your music and even ripped DVD's and have cloud access from anywhere without paying anyone a subscription and you can do this without setting up port forwarding and using ssh tunneling to get access though you are dependent on Western Digital maintaining their MyCloud web access which they're already pushing an alternative version for newer devices. I guess if Western Digital drops support, you could go back to port forwarding and ssh tunneling but then you might as well just use a Linux box as a NAS. Note, the underlying OS is Linux so you could set up ssh, get in and configure what you want if you don't mind accidentally bricking the NAS.

Es un Nas con opción a tener tu propia Nube, no es tan difícil de configurar pero incluso yo que soy ingeniero tarde mucho tiempo en optimizar los procesos que corren, ya que no puedes entrar por interfaz, necesitas entrar por consola, es algo ruidoso, si lo instalas en una oficina o en una habitación dedicada para el hardware de red y demás no tendrás ningún problema, yo instale dos discos seagate de 10tb cada uno en raid 1, funciona bien.

Basic installation is easy

Reviewed in Canada on August 2, 2018

Size: 4TBVerified Purchase

I've always wanted to set up a NAS, but didn't do it because of the price. It was on sale for $278, after reading all the positive reviews I grabbed it right away and am very happy with it.

Initial set up is very easy. Just follow their online instructions and you will get it running easily with their basic features. I use it mainly for remote file transfer/backup (mainly photos), and Plex. To set up Plex, if you are not an experienced user, it might take some trial and error to get it working properly (involved router port forwarding etc); but like everything else it is a learning process and I find it quite interesting, and rather satisfying when it works!

I read someone recommend cat6 or 7 cable to improve the performance. I'm using cat5 and am already happy with it, and will consider getting cat6 or 7 to see if there really is a difference.

There are many more features and add-ons that I can install. When I have time I'd love to explore them.

Overall if you are new to NAS I recommend it as it is easy to install and so far it is running good and quite reliable. Put it in your Wishlist, hopefully you will get a notification that it is on sale!
