Many people today are demanding more and more from their storage systems and for a select group of users (such as myself), having the ability to get access to files whilst on the go is – in some cases – a necessity. As we know, there are many free and...

Western Digital's My Cloud EX4 is a good introductory NAS for small offices, offering very good drive and data recovery, easy remote access, and basic business NAS features. It is not, however, ideal for larger SMBs or those requiring very...

Disappointingly, the use of the 'Cloud' buzzword on WD's My Cloud EX4 is a bit of a misnomer. Yes, it lets you access your files from afar, but you're going through WD's own servers - so it's technically their cloud and not yours. It's also not all that...

The WD My Cloud EX4 is a solid, attractive, and easy-to-use NAS solution for homes and small offices, providing all the consumer-level bells and whistles of a larger media center unit while maintaining a modest price point.

WD's My Cloud drive is an easy drive to use when you want to store and share data on a home network. It's also meant to be easy to use when you want to access your data over the Internet. Depending on your home network, that last part might be a little...

At the end of the day, the My Cloud is actually a pretty decent device to have on your network. Not only does it offer a large chunk of storage space for a fraction of the cost, it also cleverly provides you access to your files on the go through its...

The My Cloud EX4 isn't the multi-bay version of the My Cloud we expected. The intuitive software and setup remain, but its departure in design is unfortunate as are its poor write speeds, noisy operation and non-expandable storage.

It's almost impossible these days not to create digital “baggage.” You start by backing up your PC's data. Then the rest of your devices need more storage space — from backups to storing secondary media libraries, offloading photos, and more. If you're...

Because performance takes a backseat to features in this unit, I'll cover that aspect of the My Cloud EX4 later. The EX4 offers all of the user-friendly features of the original My Cloud, packed in a metal four-bay enclosure that boasts a number of...

Personal storage is a term you should become familiar with if you value your data. Obviously no one wants to lose critical information but where to store that data has always been a question. Thumb drives are portable but easily lost and cannot be...

Last month, we took a look at the first product in WD's My Cloud lineup. In our review, this editor found the device approachable, not only for those whom aren't overly technical, but also for those on a budget. The 2TB version that we looked at had an...

WD zet met de My Cloud EX4 een product neer dat je op verschillende manieren kunt bekijken. Aan een kant zou je kunnen zeggen dat hij niet enorm snel is en dat niet de laatste technologie gebruikt wordt. Hierdoor haalt hij ook niet niet de beste...

og konklusjon Western Digital My Cloud ser ved første øyekast ut som en av WDs eksterne harddisker i My Book -serien, men under det hvite plastskallet skjuler det seg litt ekstra maskinvare. Ved å ganske enkelt koble den til en hub, svitsj eller ruter...
