Hi. I have a friend who does photo work and is interested in either the RAVPower Filehub Plus (WD-03) and the Western Digital My Passport Wifi Drive. Basically she wants to be able to transfer photos after a photo shoot to her iPad without a computer to do some culling and light photo editing. I have the WD Wifi Drive but I think she is leaning towards the RAVPower Drive. The questions I have is what is the difference between the two models and can the RavPower read RAW files and transfer to the iPad. Thanks for your help!
