I currently use 3 methods of external storage for my laptops and for different reasons. I'm curious if others do the same and if there are reasons to choose one over the other. Currently I use: an external hard drive for backups, thumb drives for various versions of files and an SD card for holding some photos but occasionally swapping it back and forth with my DSLR camera.
What do you use and why?
I didn't find the right solution from the Internet.
