USB drives may come in all shapes and sizes these days, but they all basically give you one of two choices: you can buy one big drive to store as much of your data as possible, or juggle a bunch of drives if you want to keep things separate. Designer Hyunsoo Song has proposed an alternative with this so-called Amoeba modular USB flash drive, however, which let you sort your data on individual drives that can be used both on their own or together as one large drive. The idea there being that you can keep the drives together most of the time, and just detach the appropriate section if you want to share only your photos or videos with someone. Of course, the keyword here is "concept," but it's not exactly as far beyond the realm of possibility as some others we've seen.
