Suitable storage for photo backup
Hi, I'm thinking about buying an iPad 2 to take on a trip. Among other things I'd want to use it to store photos I'll be taking with a digital camera. I gather I can buy an Apple iPad Camera Connection Kit and use that to read the SD card from my camera.
It's important to me to have a backup of the photos. At first I was thinking of bringing an external 500GB USB drive to back up to. However, the small Transcend drive that I have needs to be plugged in to two USB ports at once to supply the power it needs -- so I gather that rules it out for the iPad.
Is there a reasonable-priced storage device in the 64GB size range or larger that will work with the iPad 2 that I'd be able to back up photos or other files to? It would need to be something attachable to the iPad via a hardware connection, not network-connected.
