I am already working on it. I have 4 memory stick slots and I am writing the software for the pic to interface it. They can not all be on at the same time. Just switch from one to another just like we use to do paged memory on an Intel cpu.
You would get the same effect as plugging and unplugging memory sticks in your slot.
Simply a place to store them and turn each one on when you want to access the data on it.
Try it. You change the memory stick without restarting and you will see the new directories. One stick for movies, One for action games, One for First person shooters, Etc.
Besides when 4 gigs are $35 and you can put four in giving you 16 gig for under $200 that is not bad.
Later....
