I saw a battery powered hard drive on Amazon that creates it's own wi-fi hotspot.
Seagate Wireless Plus 1 TB Mobile Device Storage with Built-In Wi-Fi Streaming (STCK1000100)
Does anyone know if something like this could be used to create a real time backup and store photos as they are being shot by either using something like an Eye-Fi card or the bulit in Wi-Fi on a camera like a 6D?
For the price, it is probably too good to be true. Has anyone tried this?
