If you are like most "techies", you probably have a couple - at the very least - smaller capacity microSD cards laying around which you simply "out grew" and replaced with bigger ones. Well, what if you could reuse three of them and make combine them into one big(er) flash drive? After all, a flash drive is just a bunch of NAND chips (or sometimes just one), a USB interface and a controller chip or two. And since you have all these useless micro SD cards that would be a perfect building block for your own Franken-Flash drive! We know we have though of this many times and went "nah, that sounds too much like work and a ton of hassle to build it our selves".
