Ok - so i am planning a year of travel next year (finishing university and never had a year out - have to comply to the tradition dont i? )  and may need to be out of touch of electricity for months at a time and need some way of accounting for that with my camera.  Apart from taking large quantities of batteries with me the problem of storage comes to mind.  Does anyone use these external harddrive things specially designed for photo storage and organisation i have seen around and could tell me what to look for? or should i just stick with maybe getting a load of cards? i am expecting something like 20GB of storage minimum
