You guys can see MAKE magazine's rip-off article of my project at:
Thanks for the credit MAKE, I really appreciate it....
Step 1: Find a Candidate.
Step 2: Dismantle..
Step 3: Compare
Step 4: Hub
Step 5: Install
Note: I was only placing this temporarily, if I was going to keep this mod permanent, I would glue the hub in either using epoxy or hot glue.
Edit: I forgot to mention, if this was going to be used permanently, I would coat the circuit board with epoxy, just like I do with Flash Drives.
Step 6: Flash Me!
Step 7: Button It Up.
Now you will have a "new" Flash Drive that will be sure to get some comments.
Also, there is a way, I haven't done it, but with a certain flavor of Linux, you can install Linux onto all 4 of the Flash drives in a RAID configuration, assuming you have all the same capacities.
