This concept USB drive, could potentially solve our problems by allowing us to toss all those thumb drives and find a use for the homeless microSD chips. The Collector wouldn't have any storage of its own, instead you'd slip up to three microSD cards into it and, when full, simply swap them out for more.
It would also combine your smaller chunks of storage into a single block, so those three 2GB scraps would become a slightly less useless 6GB drive. Of course, keeping that pile of microSD cards (now bound by common data) organized might actually be a bigger headache than rifling through your drawers looking for that OFWGKTA mixtape you downloaded so many months ago.
