Is this cloud storage enclosure hard drive compatible?
If you're looking for a Networked Attached Storage (NAS) drive that you can add to your own hard drives to, then this My Cloud EX2 (manufacturer's code: WDBVBZ0000NCH-EESN) is a great option. The two bay design lets you add a hard drive of up to 8TB in each slot, for a maximum storage capacity of 16TB. To instantly expand your storage even further, you can add an external USB drive into one of the USB 3.0 ports. This provides you with a potentially vast amount of storage space, which can be expanded even further if needed.

What are the backup options I can use with this NAS drive?
Backing up computers couldn't be easier with WD SmartWise Pro, which is built for Window computers and compatible with Apple Time Machine for Apple Mac computers. You can schedule backups to happen on a regular basis for your important files or for when your whole computer has made a recent change, speeding up the backup process.

An added external USB device doesn't just have to be used to expand the amount of storage you have, you can also dedicate the connected USB device as a backup location. Similarly, integration with Amazon S3 and ElephantDrive cloud services allows you to back up data stored on the My Cloud EX2 or an EX4, you can also remotely back up data to it, no matter where it is in the world. This gives you a number of backup options to choose from, which is essential for businesses and anyone who does not want to lose important data.

What apps can I use with this NAS drive?
For Apple iOS or Android devices, WD photos and My Cloud apps are available, providing you with access to the NAS drive from anywhere. You can greatly customise the My Cloud EX2 Ultra with a number of apps compatible, such as iTunes or Plex. Plex is an app that can be used to organise your media files, and can be downloaded onto a number of different devices such as Smart TVs, computers, tablets and more - where you can stream your content to them. 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.

Can I stream with this NAS drive?
The built-in DLNA feature and powerful NAS system mean you can enjoy high performance streaming that is lag-free. Combined with the Plex Media Server, your HD content will be organised and prepared for streaming to your PC, Smart TV, media device, games console, or other certified media player.

What other features are there?
User profiles can be created and then given access to the My Cloud EX2, and portions of the drive can be assigned to individuals or groups. This makes it perfect for small business which want to use the My Cloud EX2 Ultra as a server for their employees. An UPS (Uninterruptible Power Supply) can be connected to this NAS drive via USB or network, which will provide you with a temporary power source for your source for your server should the main power source ever go out.

Support for iSCSI gives you the ability to make a virtual storage location for your computer, as your computer believes the drive created is a local hard drive. This allows you to manage storage over long distanced and transfer data over a network rather than locally.

Rated 5 out of 5 by from Superb product The WD EX2 Ultra NAS is a well built, quality product. It was very easy to set up and used in conjunction with a Gigabit router is extremely fast. I have set it up as a Raid 1 device, safe in the knowledge that all my files are now backed up automatically. Previously I used two WD MyBook Live devices and third party software to achieve this but it was not the most elegant solution. Would recommend highly.

Hi might be a lame question, I am new to personal cloud storage device. Does this product require specific 8 TB hard disk to work or can I simply connect my external portable 2 TB to this and use?

Asked by: Vicky
Sorry you cannot connect your existing portable drive to it. The unit does not have any drives in it when purchased. It will accommodate 2 drives each of which can be up to a maximum of 8TB a couple of these would be ideal

Do both enclosures need have drives installed for this to work? For example; can I just install one 6TB drive in one enclosure and leave the other enclosure empty?

Asked by: paul26gh
You can use the device with only one 6TB drive but you will have no option for RAID.

Can I access data from a disk swapped out of a similar enclosure? So if one enclosure fails then the data could still be accessed by simply swapping enclosures.

how easy are these drives to actually connect to a MacBook pro, as have tried a seagate personal cloud and MacBook does no recognise and cannot be used

Asked by: youandme
It would depend on your version of the Mac OS, as the method for connecting a NAS drive has changed slightly between versions. You may need the IP and MAC address details from the NAS drive to establish a connection.

Can this work within a network of both PC's and Mac's without issues?

Asked by: salv
This should not be an issue, NAS drives do not transfer data in the same way as local drives, so drive file system compatibility is not an issue.
