Misleading description - this is a 2x2TB NAS

I bought this thinking that it was a 2x4TB NAS. The description says that has 4TB of storage, and that the data are duplicated for backup. It was not clear to me that this was a 2x2TB. Disappointing! The NAS itself is fine and was easy enough to setup.

Easy to setup, Best for backups

This unit can be configured in RAID-0 or RAID-1. RAID-1 is the mirror mode unlike what others wrote. This is the safe mode but it is slower than RAID-0 and effectively has a capacity of 2TB (2TB+2TB for mirror backup). I use this unit as a backup storage in RAID-1 for another NAS (WD EX4100). It is perfect for backup since speed is not that important. If you need performance you can still use this NAS: Configure it in RAID-0 and plug into it a portable USB disk for backups. Because if any disk fails in RAID-0, the whole unit loses all data on it. With a USB backup, it does not matter. Too bad you cannot schedule USB backups automatically. You need to start them manually. Still, it might work for you. RAID-0 offers the full 4TB of capacity and double the read/write speed. In summary, this is a very good and reliable NAS for light duty, or central backup of files (including Mac Timemachine). Other NAS have more features, performance etc.. But they cost also double or triple the price or more. This is still way better than a single disk NAS and setup is doable for non experts. Note: by default cloud access is enabled. consider disabling it. configuration is more complex in cloud mode and it is not entirely safe to open your data to internet imho.

Seems to work well

Works well. Product only has 2TB of space in the default RAID1 configuration (2TB x 2TB). This is not clarified on the product information page. "WD Sync" software must be downloaded from Western Digital's website in order for the product to function correctly as a cloud drive.

I can't believe I fell for this marketing trick! It's 2T Mirrored

It is not 4T mirrored, but only two, TWO Terabytes of mirrored data! Yet they make it sound like you get 4T mirrored. Buyer BEWARE!

  • from Richmond Hill, ON

RAID 1 is not Mirror

RAID1 is not a MIRROR drive configuration - it is a STRIPE configuration and it does not offer any data redundancy. If you will configure two 2GB drives in MIRROR (which is RAID 0) then total storage capacity will be just 2 GB (not 4)

  • from St-Colomban, QC

Good features for the money

A personal Cloud server, easy to use and manage, many features to today's needs. Great bang for the buck!

The best I owned so far

This is so far the best NAS I owned, It does exactly what is supposed to to. I never had a bad experience with any of my WD products. And it's hilarious some people call this a "scam" just because they are not aware of Raid1 and Raid 0 configurations. They need to get themselves educated before giving low ratings on great products.

  • from Winnipeg, MB

Great NAS and Backup solution.

Works and functions exactly as expected. Setup was fairly straight forward and it only took about 5 minutes to start using the device. Works equally great with both mac, windows pc and iPhones.

  • from Montréal, QC


Dont know why poeples say its a scam when its really not a scam.... maybe because poeple see only 2TB free space , and if you really know thats because by default (out of the box) the wd my cloud mirror is set to RAID 1 and thats why you only see 2TB of space .... if you takes some time to set it up correctly and set it to RAID 0 you will see your FULL 4TB free space .... mine is working correctly and i can access my files from everywhere i go....

  • from Richmond, BC

What a scam !!!

Everything about this add and the big sticker on the box suggests you get 4 TB of storage. Only a tiny sticker on the box states that there ate two 2 GB drives installed in a RAID 1 configuration. Best Buy clearly stated that if I opened the box there was no refund, only an exchange if it was DOA. I can't believe how close I came to getting stuck with this.

  • from Mississauga, ON

Works as advertised

No issues yet with this device. Works as advertised. I like the Plex integration

Great Backup and NAS Drive

I was looking for NAS Drive to use it for local backup and access it online. The WD My Cloud Mirror 4TB was a good fit. It has built in backup software as well as it keeps a second copy of my backup data on the second drive (It comes with RAID 1). In case one drive fails, data is safe on the second drive. Moreover, I am using it as a network shared drive and accessing data from two computers in the office. Simple to use, automatic backup, online accessibility. It has option to create additional shares to save photos, music for which you can allow access to friends or access online from anywhere. Customer Service is very friendly and they set it up on my computers. Completely satisfied.
