WD External drive M'y cloud mobile

Finale what I was looking for. ED wireless content accessible anywhere in the world.

  • from Nanaimo, BC

Great way to consolidate files.

I used this drive to consolidate all my files from my various computers in my home. It makes transitioning from one computer to the next virtually seamless. It took a little time to get things set up just right, but has worked beautifully ever since. It also has a great backup feature, so you can just plug your backup drive in and it will sync everything for you. It's also easily accessible with my various devices via DLNA and SMB. I would highly recommend this NAS for anyone looking to simplify file access/sharing across multiple computers and devices in their home.

  • from Calgary, AB

Steer clear from this drive!

Get yourself a standard USB 3.0 drive instead of this. This u it can't be mapped to a drive letter so windows will not use it for any of its backups. Most third part backups wesp dialog cloud backups will not recognize this since it doesn't have a drive letter. The iOS apps do not work correctly. Can't auto backup pictures from devices. So basically this is an over priced over glorified USB drive that connects as a network. Software is outdated and useless. If your just looking for a phical drive to store data on, get a standard USB drive. If you want real cloud storage, upgrade your iOS cloud. Onedeive or Dropbox. Even go to a third party cloud base backup. this WD Drive is not worth it and the features don't work.

Save Your Money

Works great if you don't wish to actually save any files on it - crashes every time you try and copy files onto the drive and takes forever to come back up. Even if you do manage to get a couple of files on the drive before it crashes, the process is excruciatingly slow. Save you money and pay extra for a NAS drive that actually works.

  • from Victoria, BC

NOT plug and play ...

For local use should just be plug and see in explorer, not a sign up, not a bunch of win10 configuration, really not impressed, might be happier once can get it to be seen in explorer ...

I am a big reader of reviews. The mycloud had pretty good reviews. I read the negative reviews, the horror stories of losing everything and the horrible customer service with Western Digital. I thought that the people who had issues probably did something or didn't know how to do something and it was somehow their ignorance that got them in that spot. I am here to tell you, STAY AWAY. About 6-8 months of working great, I could no longer connect to the drive. I called Western Digital and learned that the network port no longer worked. I had no way to connect to the drive, therefore, all my picture of wedding, baby's first year and a half and all family photos were stuck in that little cheap box that I bought for about 250.00. Western Digital advised it was still under warranty. GREAT! Actually, not so great. Data recovery is not included, and if I want my family and baby photos, I am on my own. Well, here poses the next problem. If a company opens the drive to extract the data, it will void the warranty. FANTASTIC! I did read on Western Digital that if a company opens the drive for data recovery, that it will not void the warranty if they provide a letter, on company letterhead, saying that they did this. PERFECT, that solves that problem. Not really. Geek Squad could do data recovery, but they would not provide a letter. Also, to add insult to injury, Western Digital told me that I am responsible for sending back the defective unit, on my dime. After some arguing, they agreed to provide a prepaid UPS shipping label. I would highly recommend staying away from this product. I do not know how the other Western Digital products, but be wary of poor customer service with the manufacturer.

  • from Toronto, ON

Great concept, but they've dumbed it down for the masses

Would have been great, except that you can only sync stuff IF you follow the dumb Windows file convention (using My Music, etc.) all stored on your C: drive. For those of us old-school people who separate data from software on different drives, it's pretty useless. I have no space on my C: drive to store my data, nor do I want to. it's pretty dumb that we can't specify other storage locations. Except for this (very limiting) feature, this would have been great. Sadly, I must return it.

  • from Montréal, QC

Worst performance

initially, it was okay, but once you use more than around 75% of the storage, the performance drops significantly. I know it's a 5400 rpm model, but it feels even much worse than that. Definitely would not recommend.

  • from ottawa, on

lousy user interface

Sure it backs up files but it is not easly, intuitive nor friendly to access the files from windows explorer. You need to use a browser to move files individually. You cannot easily map a directory (like google drive).

  • from Lethbridge AB

Product as described

Good product

  • from Toronto, ON

not a stable product

I can access the setup page only once after the power on this product. Then, I can't access this page even I use Mac address. I make a new directory as the backup folder, I can see the files transferring to the cloud on the web page, but, I can't find out the folder on the cloud. I have to return it to the shop.

  • from New Glasgow, NS

Great product

I had some trouble finding the correct web site to download the installation software but once that was taken care of everything has worked great. All expectations met or exceeded.

  • from Shannon, QC

Very good product Impressive Speed....

I'm happy to no snags installing this drive window PC discovered it right away and the download for back up for pc to drive was very good since it was all done by network only no wire. That is great by the way, I love the fact that I can acces it anywhere with easy acces and a handy app for my iPhone.

  • from Edmonton, AB

Does what it's supposed to.

I purchased this cloud drive because I wanted to have some control over my files. But it's not my only cloud back up. Best Buy delivered the drive quickly after me placing the order. No issues there. One issue I did have upon installing was with the firmware update. Struggled some time before I found info on the web regarding turning off the drive in the process. Once done, it works. Still have not used it much except for uploading mobile files, which was my main priority but I'm sure more uses will becoming down the road.

  • from New Westminster, BC

Very Happy

This product was better than expected and on sale was a good value. Easy to use with good speed.

  • from Toronto, ON

Very Good Product

It's a great product but only when it is handled correctly. It is meant to be a media server instead of a usual network backup device. It is designed as a home network source of movies, music and photos. It should be connected with RJ45/CAT5 cable to the gigabit port of your router instead of using wifi to connect. Every change will be followed by rebuilding of multi media databases such as thumbnails and so forth. So you don't copy large amount of files to this drive using the bundled software which will keep rebuilding everything for you and will slow down the copying. I believe that the initial copying of large amount of files should be done by connecting this device to your PC directly as an external drive. Then copy all the files from your PC to the shared folders of this WD drive. Then re-connect it to the router port, then rebuilding the media database using the downloaded WD software. When you keep copying files to the device while it's trying to build the media database, the database may fail to synchronize with the new files. Wait for the building to finish, then manually run another rebuild, or the much quicker re-scan. Actually you only need to re-build when the re-scan doesn't work for you, say, the thumbnails of your photos won't come out. The CON of this product is that the manual doesn't explain very clearly about how the different download application work and be used for. It is very confusing at first to figure how they work and what they are used for.

Alright but not amazing by any means...

I bought the 4TB My Cloud from my local Bestbuy here in Winnipeg. The store was awesome as usual. Here are my the pro's and con's of the MyCloud based on my experience after 3 weeks with the My Cloud. Pros: Lots of space, easily recognized on home network, great DLNA streaming to smart TV's, Apple TV2 and all mobile devices. Also, the mobile cloud app is okay. Not mind blowing but enough for the average user. It's slow but not too slow where you get annoyed. Cons: If you are doing what i would call a core dump of files on to it for the first time it could take days. I did a server backup of 400 GB's and it took about 4 days. It was excruciatingly slow. TIP: Use 3rd party software if you want to do large sized backups. Bundled software is weak which leads me to my big issue with the WD My Cloud. The drive has the possibility to be amazing BUT the bundled software is SOOOO weak. The nice interface advertised to manage the drive and shares is so slow. I don't even words for how slow it is. The WD Software that you can use to access drive folders from your PC and Mac is excruciatingly slow and often will produce errors if you upload files or folders of a significant size. The drive has a CPU and Ram that just can't handle the volume of data that power users would throw at this drive. This drive is targeted to power users i believe so it's a big weakness. TIP: Don't use any of the WD software beyond the setup of the drive. Once that's done use 3rd party backup software and network share the drive on all your devices and computers. Uploading and downloading from the drive is way faster without the use of any software provided. Another TIP. If you get frustrated on the drive relax. I noticed for whatever reason after a week or so the drive became way faster. I'm not sure what it does internally the first week or so. Now it's working fast (again without WD software though). So give it a week or so to do it's thing. Also go in to Twonky Server included with the drive and disable the indexing. You will thank me for that tip. :) Conclusion: Would i recommend the My Cloud based on my experience? Yes if you can live through a little setup frustration. Does it work as well as advertised by WD? No way. Not even close. WD market the drive likes it's a dream home cloud solution. My opinion. WD My Cloud is a little bit of a storm cloud. Hope my review helps you.

  • from Ottawa, ON

Not Bad

I was looking to purchase a home NAS for some time and this was finally it I had some glitches setting it up, the instructions are terrible so I called the WD help desk and they provided all the help that I needed. It worked well. I now have a PC and iMac connected to it. I will try the MacBook Pro tonight. So far, I am very pleased with it.

  • from Rutland

Great product

This product is being used as a home media server; streaming movies and music to various media devices/game systems throughout the home on wired connections. For this, it's working perfectly. Setup was simple, and copying files to the myCloud is no problem. Quiet operation and the ability to shut off the LED is nice. Transfer speeds have been great as long as added stress (eg. downloading) isn't put on you network while transferring files to the myCloud. Cannot speak on wifi streaming or remote operation as it hasn't been attempted yet. I was on the fence about this product because of the varying reviews, but I'm sure glad I went for it. It's added a lot of convenience and space to my home network. I think the bad reviews come from users who do not have gigabit routers/switches/devices etc, or they are having some issue with their wifi signal/setup. Overall, this is a great product and you should not hesitate to give it a try on your home network.

  • from Ottawa, ON


The installation software provided by the WD web site did not work (no software comes with the system, it must all be downloaded). The software made it through most of the installation but then stopped. I tried 4 times. Called their installation support number and received quick, outstanding help (thank you). Basically they walked me through a manual method to install, which was easy once I saw the method. I had (and still have) issues in backing up multiple large files (copies of my PC backup files). Day to day use, it works well. I tried the DLNA service with pictures to my TV, worked fine. My PC has a gigabit wired connection and transfers are very fast (as fast as my computer can feed it).

  • from Toronto, ON

Excellent product

This is an excellent network disk drive. I don't need or use any of the fancy features (I turned off as many as I could), I just need a drive I can put elsewhere in my house so I can back-up my computers disk drives to it, and this works great. The drive is huge, reliable, low-cost and simple to use. I suspect the criticisms of the drive are from people using it from their wireless laptop computers and they don't understand how huge the files they're transferring are.

  • from Etobicoke, ON

Works well

Good price for what it does... DLNA certified server + 4TB of storage, can't go wrong. Not the greatest DLNA server, found some issues when browsing folders from my LG Smart TV, but the issues can be worked around and could be related to the TV.

  • from Mississauga, ON

Amazing Product

There are allot of negative reviews on this product simply because people have no idea how to properly set this device up. First of all you need a gigabyte router (look it up), and you need your computer motherboard to accept gigabyte speeds if hard wired to the router. If you have hardware that is gigabyte and not the 10/100 stuff from years past, you will have transfer rates of 70 megabytes per second like I am right now having backing up some files. Next if you have wireless pc's, the file transfers will easily do 30 megabytes per second if you use the latest wireless standard "AC" adapters to an AC gigabyte router. I'm using a D link DIR-868L and the speed transfers is crazy fast. So basically, if you complain or are scared that transfer speeds are too slow, you don't have the right equipment to take advantage of this unit's capabilities. Don't complain about this product and find out why it's slow as I can guarantee it's not this device. It's fantastic...again...when you have the right equipment to work with it. Rui.

Great hardware but UNINSTALL WD SmartWare

I have been using this product for about a month and it is a great piece of hardware. The set-up is easy, the access speed is fast and the support is good. CAUTION However, the only caveat is that you MUST UNINSTALL WD SmartWare that gets installed on your computer. SmartWare is a back-up program that lets you either continuously back-up your files any time they are changed or set up a schedule. However, whoever wrote the software is a complete idiot as it takes up a 100% of your computer resources, crashing everything and making your computer unusable. Please ensure you DO NOT rely on WD SmartWare as it will cripple your computer. After uninstalling this software, my computer is now back to normal. I will now rely on manual back-up methods to the drive rather than SmartWare. I also called WD to file a complaint about this software.

  • from Richmond, BC


Performance is unusualy slow and the device is generally unreliable. Not a device you want to trust your precious DATA on. Until Western Digital resolves these issues I would recommend looking at an alternate solution.

  • from Langley, BC

Straight forward setup but poor performance

I purchased this two weeks ago and set it up at home so that both my wife and I could back up our files, and share media. Unfortunately I found my data got corrupted during transfer and I could only delete some files when using the WD software as opposed to using the network connected drive in my Finder window. I brought it to work with me to direct connect and trouble-shoot, but after a couple of days of trying a few different options I'm returning the product since I can't chance backups being corrupted. Like another review I too found the file transfers slow. Perhaps this is an issue when running on a Mac only? Either way I'd prefer the old plug and play method of backing up to potentially losing the data.

  • from Calgary

Serves the purpose

I bought this to make my sensitive available from anywhere as a private cloud as I wasn't feeling comfortable with other public clouds and it's serving that purpose very well. Have a few issues viewing some media files from my Sony TV but blaming that on the client rather than the device as the same content is viewable on my smartphone and laptop.

  • from Nanoose Bay BC

WD MyCloud 4TB NAS

Easy to set up, I created four folders and also use Acronis 2014 to backup my files and partitions as this drive has room for it all. Obviously it works at a hard-wired network speed so whatever your speed is that is the speed it will transfer files at. Mine is at gigabit wired straight to the system and it is not bad for file transfer speeds. Wireless is slower of course. I have already initiated a firmware update and that went without incident. Would I recommend it? Absolutely, at that price it is a bargain.

  • from Vancouver, BC

Not So Bad

I purchased this to back up 3 different macs that I use. I was tired of plugging in and unplugging the backup device I currently have each time I needed something off a different computer, so backing these up on the one network drive has been really helpful and convenient. I find the backup times to be a bit slow (one backup was 315GB and more than 18hours later it's still going), and it was a challenge to set up and be able to access away from my home, but once that was ironed out it's been really useful, especially when I'm traveling and need to grab a file back home. I would recommend it for mac use.

  • from Brampton, ON

Good product

Easy to setup, web interface has improved from the previous model. I use it mainly for media streaming and it performs well with a hardwired connection with all my devices. I will most likely buy another one or two in the near future.

  • from Toronto

Great device for backup and storage

I found it quite easy to setup, but I suggest you take some time to understand all the features and install options. I did not have bad experience with the install as the previous review mentioned. I liked that I could go to the WD setup website and download the various apps. You really only need to use the setup app from one computer, but it basically works out of the box. Once it's plugged in and on the network, you can just access the device directly if you choose to. You would use the apps or web config to add users, set various options etc. For automating backups, I installed SmartWare on all my machines, seems to work well and price was right (i.e. free). I bought it for use at our business, where we have 4 computers, mostly for backup. You can access your drive from anywhere outside your home or office, which is really handy but you have to go through the WD portal for that I plan on buying another one for home use to backup and use a media server for our home computers and ipad, etc. Gave it 4 starts because I think WD could do a better job outlining all the different ways to access and configure the device. You can download their app to configure certain features but it also allows you to perform the configuration with it's web-based UI right off the drive, and the look and feel between them was not consistent. You can plug in an external drive using the USB port to do things like copy media or clone your backups which is a great feature. Overall great value and feature set for the money!!
