Storage - No such thing as too much.

[Sean Setters]

If you have a laptop to transfer images, a USB flash/thumb drive is a lot cheaper than a similarly-sized CF card. When I want to China, I took a set of three 64 GB thumb drives to supplement my HDD with external backup copies.

Good point.

I am OK w/ two copies. One on the Laptop and one on the 1TB external USB drive - I haven't amassed more than 64g in a day yet. When the external gets full, then I know I will be in a lot of trouble. I also get pretty quick w/ the "this pic isn't going to make it" FYI, I have a friend w/ the Nikon d800 and he moans about storage even louder.
