Instantly increase your storage to meet your needs
Store and backup your precious memories in a central location with this WD Mirror 4TB NAS drive (manufacturer’s code: WDBZVM0040JWT-EESN). Two 2TB WD red hard drives give you a potential maximum storage space of 4TB. The hard drives have been designed to perform well, even under the constant stress of 24/7 operation, which makes them perfect for this NAS drive. To give an immediate increase in the storage space an external USB drive can be inserted into one of the two USB 3.0 ports, for a quick and easy way to meet your growing needs.

What kind of backups can I set up?
You can back up your Windows computer via the WD SmartWare Pro application or Mac computers via Apple Time Machine. The backups can be scheduled to happen automatically, covering a single folder or the complete computer. Alternatively, you can set backups to automatically occur when a change has been made in the folder/computer, speeding up the backup process.

To ensure files and backups are stored safely on the NAS drive and not lost during a rare disk failure, WD has configured this to be RAID 1 as a default. This disk management setting essentially uses one of the two hard drives to ‘mirror’ content that is stored on the other. This means you have the same content on the two drives and if one were to ever fail, you would have a backup available. This setting also limits the stock storage you will initially have to just 2TB.

Any attached USB devices can be used as a target for backups, as well as being used to increase the overall storage of your NAS drive. Likewise, the compatibility with Amazon S3 and ElephantDrive allows you to backup what is stored on the WD Mirror to the cloud. Owners of more than one My Cloud Mirror or a My Cloud EX4 can arrange for information on this NAS drive to be saved remotely. This multitude of backup options help to secure your data to make certain it doesn’t get lost when a drive failure does occur.

What apps are available for this NAS drive?
Free up space on your Apple iOS or Android smart device, with the My Cloud app, allowing you to save and backup your pictures and videos to your own personal cloud storage. Apps can be installed onto the WD Mirror, and as a default, http downloader, FTP, P2P and web file viewer are already installed. These apps allow you to automate and schedule downloads/backups to happen through a web link, share files and view the content of the NAS via the dashboard. Third party apps can be installed as well, such as WordPress, Plex and aMule, so you can customise the Mirror to suit your needs.

What can I stream to with this NAS drive?
The DLNA and UPnP certification of the NAS drives means as long as other DLNA and UPnP devices are connected to the same network, media files can be streamed to the device. Smart TVs, media players and speakers are just some example of such devices. Installing Plex on the NAS drive also lets you stream to any smart device that can install the Plex app, opening up the range of different devices you can stream to.

What other features are available?
You can create users and give them access to the WD Mirror. Users or groups can then be assigned portions of the drive to either share or use themselves. This makes it perfect for small businesses to utilise the WD Mirror as a server for their employees. To avoid interruptions in the constant operation of this NAS drive, an UPS (Uninterruptible Power Supply) can be connected via USB or network, giving you temporary power if your power supply goes.

Rated 5 out of 5 by from Fantastic value for a personal Clous I bought this unit about 2 years ago - its fantastic , easy to install manage access form anywhere in the world. I did access my data from Singapore, Cape Town - SA, Europe and it works perfectly according to the local internet speed you have .

Rated 1 out of 5 by from Far too complicated I bought this as a 'plug and play' type device. It isn't. It takes a lot of configuring and you need IT skills to set it up. The instructions are very poor and the WD support isn't much better. Unless you are a 'techie' I would avoid it.

Asked by: Jitesh

I think the naming of these drives is slightly misleading. The single drive versions are obvious enough. 4TB gets you 4TB. But the 'mirror' versions are sold as 4TB when in fact when being used as they are intended, you get 2TB storage.  

Asked by: chris82
Understood. But if the word 'mirror' in the product name is to imply the raid setup, the storage space in the description should be the space available in mirror mode. It's not a '4TB mirror' drive is it? It's either a 2TB mirror drive or a 4TB standard drive... the way they name their products is trying to claim the best of both.

Please can you alter the description to better reflect the products actual features. This hard drive is a RAID device and comes configure to mirror 2TB onto a second drive.
Asked by: Customer
exactly... very misleading yet they have not changed the description since you asked 2 years ago!

Hi, will this back up both Mac and Windows machines? I have data on both and would like to be able to back them up in one place. It can be in different files as long as the NAS drive can store both sets of data?

Asked by: Sammyez
The item will be set up for NTFS use as long as the Mac will work fine with this file system then it will work.
