The DLNA Certified Western Digital Mybook World 1TB http://www.amazon.co.uk/Western-Digital ... 605&sr=8-1
Works very well indeed with My Revo Radiostation. It has TwonkyMedia server preinstalled and is compatible with just about every imaginable audio, video and picture format. It also allows trial access or sharing of your media worldwide, via http://www.mionet.com/
which is normally $7.99 per month. https://mionet.senvid.net/mioNetWeb/get ... eID=AWDNAS
A massive 198 page user guide is downloadable from here http://www.wdc.com/wdproducts/library/U
... 705013.pdf allowing you to browse the features.
If there are any Reciva users lurking, you will be glad to hear that the Mybook is happily working troublefree with my Logik IR100, Ministry Of Sound and Streamtime Reciva radios.
