So I'm trying to figure out a way to store my photos while I'm away traveling. It's more practical for me to buy an extra drive rather than a bunch of SD cards, due to expense. (both of my cameras use SD)

Something I need to consider is that I'll be gone for two years, and probably won't have much access to electricity during that time. I have a solar panel which can charge my camera batteries by way of 12v DC adapters. In any case....

I'm considering the Jobo Giga One 80gb hard drive:

Does anyone have experience with this particular drive? How well does it work for you? How is the battery life?

Any other suggestions or recommendations are welcome.
