Hi Robin,
What I do is store all my images on an external hard drive. I capture all the necessary data and store it on the laptop's hard drive while I am in the field and then move it all over to the external hard drive when I return inside. This way I don't have to worry about filling up the laptop's hard drive and it makes it easier to archive all of your images.
You can purchase a 1TB external HDD for $200 these days.
