USB flash drives are the modern floppies really. You can get one with a few GBs for literally pennies to the point where you can even get some "promotional" flash drives for free, similar to how in the past people gave out "promotional" (writing) pens for free. On the high end side you can have flash drives with as high as 2TB of storage (though the only one i've found is a bit bulky and the more regular sized one has "only" 1TB of storage).
No satisfying chunk sound though :-P.
