You should definitely consider the hard drive option. For less than a $150.00 you can get a giant hard drive that will hold everything. I DIDN'T do this last year and ended up with a virus that wiped my hard drive. I fixed it, invested in some disk recovery tools and got almost all of my important files back, but I certainly don't take any chances any more. Fry's will have good deals sometimes, too, and I saw some disks at Costco for a good price but I'm not sure if they still have them.
