Summary: I purchased this product like most people, as backup device and storage area for my media files. The transfer rate of large 4G files is less then advertised. I had to directly connect the WD Duo to my laptop which is a strait 1 Gps connection. With antivirus turned off (or on, it didn't make a difference)the max transfer rate is 30MB/s Oddly trying to transfer wma/mp3 files using the same direct cable method only allowed for 3 MB/s!!!!
Summary: As a simple NAS, it gets the job done. On my Gigabit network I can treat these drives as local drives. However, a lot of the special features don't work well: --The Media Server on the duo systems is a proprietary DLNA server (on the single drive systems they use Twonky). I have not been able to get it to be recognized by any of my systems (PS3 and Windows). I plan on changing over to Twonky, it's just extra work and probably voids the warranty.
Summary: After trying this and finally returning it for the reasons below, and trying several other similar boxes, I discovered something the world apparently doesn't know yet: On a Mac system, don't use the RAID setup included in any of these multi-drive external hard drive/RAID boxes. Set up AS ONLY JBOD. Then USE ONLY YOUR MAC OS DISK UTILITY TO SET UP THE RAID. All problems are solved that way!
Summary: I was looking to upgrade my current NAS to allow further music and films to be added in the coming months and probably years and decided to go with this as i have never had problems with WD equipment and have about 6 external hard drives made by them. This comes with some great little add ons and the web based dashboard looks slick. Thats where the good ends.
Summary: I've had my drive for several months now and think it's been long enough to write a quick review. I bought this NAS because it's from Western Digital. Having used their drives for many years it seemed logical they could produce a decent NAS box. Yes, and no. There's no point my going into lots of detail about the features of the drive and how it all works as this done elsewhere here.
Summary: The WD My Book Duo has a lot of promise and is fairly well packaged and organised, however after just 2 months one of the hard drives failed and I have had to send it back to WD. After speaking with them onthe phone a ticket was raised but I had to pay for the postage and insurance to get this back to Swindon after such a short time of working. I think this is very poor service from such a leading force in the market place.
Summary: I have been playing with this HDD now for 5 days. On the positive side the features that are advertised by the manufacturer exist and provided that they were working, it would all be a great piece of hardware, e.g. - accessing your data from anywhere around your house/flat wirelessly - accessing your data over the internet - uploading your photos from your mobile device or tablet and sharing with the rest of the family, etc.
Summary: I thought I'd purchase this device after having many WD (internal) drives in the past and having absolutely no problems whatsoever, and very long life cycles. What a mistake that was. This drive is one of the poorest implementations of external storage I've ever seen. 1. The DNLA server is useless and only decides to show up randomly across my network, even then it can't actually stream any media to any device because apparently all the media is either corrupt or just...
