Let's start by briefly explaining what this is supposed to do. Connect it to your router (via the supplied Ethernet cable), plug it in and access the WD Dashboard (either through the software you install from the WD site or through the Network folder on your Start menu). From there, you need to register for the WD MyCloud service - this enables you to view files (music, video, pictures etc) through the WD2go website or the WD apps.

Unfortunately, I kept getting error messages saying unable to register. This was due to two things - firstly, my router (BT Hub 4) needed changes to allow port forwarding and I'll get onto the second issue shortly. Now, I'm not techy in any way so took a long time to figure out how to do port forwarding (the WD forum has details on there). I'd have thought that if this device doesn't work with certain router settings, there would be clear instructions provided to resolve this. A quick start up guide is not useful, neither is a 142 page user manual considering this is advertised as a plug and play device. I eventually registered for the WD MyCloud service and received the confirmation e-mail. From there, I successfully transferred some video files from my computer HDD to the Video folder in the NAS. I could then view those files on my devices (iPad and iPhone) so all was well.

Unfortunately, this NAS is plagued with server issues at WD's end. Although you can transfer files to the NAS so it operates to a point, you cannot view these files in the WD MyCloud service unless it's working. There have been server issues at WD's end for about 2 weeks and no current details of when they will be resolved.

Having read such mixed reviews and researched the options, I finally bit the bullet and bought one last week. I have a 2TB portable drive which is full and goes everywhere with me, so I needed to ensure it was backed up somewhere else. My partner and I also want to share access to photos, music etc.

I unpacked this and plugged it all up with my breath held and... so far it has simply 'just worked'. Everything has been perfect without any setup. I did configure shared folders and security/access rights of course but the drives/folders just appear on all devices within the home wifi network including Windows 7 (via mapped drives), Windows XP (using WD software), iPhones and iPads using the appropriate apps. Need to test with partners MacBook next but am optimistic.

It has also worked seamlessly away from home. I can still reach back to my cloud from any internet connection. My mates are delighted that I can show them 10 years of photos whilst in the pub...

Yes - uploading data is slow even over a wired connection at home, but as this is for occasional backups, e.g. the latest set of holiday snaps, I'm happy to leave it uploading overnight or whilst at work. Retrieving data, even away from home, has so far been impressively quick.

The only real alterative to a drive like this is the annual cost of 'real' cloud storage, which has the benefits of redundancy but other risks also. So long as I still have my data in two places and generally keep those two drives in different places, I see this as a good cheaper solution.

Update - appeared to my partner's Mac as soon as I turned it on. Connected as guest initially and thus only public folders visible but easy to hit the 'connect as...' button to login using user credentials, revealing the private folders.

I can see a lot of conflicting reviews, as there are with most NAS devices. This is mainly due to variations in people's network setups/speeds.

Put simply, if you're not using the latest technology, you're not going to be able to take full advantage of the My Cloud or any other NAS device. It will work, but slowly. I think a lot of confusion is created by the difference between megaBITS and megaBYTES. Transfer speeds are often quoted in bits rather than bytes, yet file sizes are commonly known in terms of bytes. For example a transfer speed of 100Mbps is not the same as 100MBps. The capital B makes all the difference. 100Mbps (bits) actually translates to a transfer speed of about 12.5MBps.

Now lets talk ethernet. Ethernet is the standard internet cable you plug into the bag of your router to connect to your PC or from the My Cloud to your router. The My Cloud is a gigabit ethernet device. That means it can potentially transfer up to 1000Mbps (megabits), or roughly 125MBps (megabytes). Most older routers are limited to 10/100 ethernet, which is limited to 100Mbps (megabits), or 12.5MBps (megabytes). The difference is obviously huge. At it's peak, that means a 10GB 1080 movie file will transfer in just over 13 minutes on 10/100 ethernet, but barely over 1 minute on gigabit.

I imagine a lot of people are buying the My Cloud expecting the quoted transfer speeds and being hugely disappointed when they're capped at around 12.5MBps. To check, look at the back of the My Cloud. There are 2 lights next to the ethernet port. The top light is the activity light. Ignore that one and look at the bottom light. If it's a dull amber looking colour, that means you're connected via 10/100 and your speed is limited.
