We talk a lot about backing up your files here at Apartment Therapy, but that's because it's so, so important. You never know when your hard drive will fail, or when something might happen to your backup. Personally, I don't back up that much data--while I have an extensive music library, I'm not attached to the files since I can listen to almost everything via services like Spotify, and I know I can re-download any applications I need. But years of photos and creative endeavors aren't replaceable, so in addition to things like Apple's Time Machine and Dropbox, I like to save these files to a tiny thumb drive that I always keep plugged into my laptop.
These days it's amazing how small thumb drives are getting at such large capacities. Plugged in, the 32GB drive I use sticks out less than 1/4 of an inch. And, drives like these are amazingly cheap. While flash drives certainly aren't always 100% reliable, they make for an ultra-convenient secondary or even tertiary backup.

The drive I personally use is the 32GB SanDisk Cruzer Fit. It's been working well for me, sports a tiny footprint, and is available for only $20.28 (free shipping) on Amazon.

If you want something even smaller, and looks matter a little more, the Elecom Super-Mini USB drive is another option, though will cost you $43.40 for only 4GB. It isn't the most economical on this list, but it is available in a number of colors and is one of the best looking.

If you're looking for some extra reliability, the Verbatim Tuff-'N'-Tiny claims to resist water, dust, and static. It's also about the size of a penny, super thin, and available for $25.58 for 32GB.

Featuring the same form factor and water resistance as the Verbatim, the Super Talent Pico-C is another option with a higher bling factor. It's available on Amazon for $33.75.

The LaCie MosKeyto is another pricier option at $46.99 for 32GB, but unlike most tiny drives, it actually tethers its cap to itself. If you keep your drive plugged in, it's pretty easy to lose the cap, so it could be worth the price.
The nice thing about the small form factor of these drives is that you can always leave them plugged in, even when you stow your laptop away, making it easy to copy over important files as you create them. Do you use a thumb drive as part of your backup repertoire? Let us know!

The bad things about these large small USB sticks is that they're easily lost. They also use up a USB port. Maybe you should do an article about tiny USB hubs. Compare speed and how much storage they can actually provide. 8 port USB hub, full of 64 Gig USB sticks is a respectable amount of storage. :)
Yes, I agree they are easily lost, but at least the last three look like they can be attached to your key chain. If you lose your keys, you have bigger problems than a $20 UBS key :)
usually these ultra small drives suffer in speed which is where their big brothers still shine. as the physical size goes down and storage goes up, speed can be a huge issue. Moving 32gb at less then ideal speeds is not fun.
I bought a handful of Verbatim Clip-IT flash drives a while ago because I needed cheap/give-away-able drives... they're a pretty small form-factor, and an added bonus is that their form allows them to be used like a paperclip. I constantly find myself clipping them onto the thin adjusting straps on my backpack, and not having to worry about them sliding off.
