Check this out… the SanDisk ‘Crizer FIT’ thumbdrive.
I searched for ‘world’s smallest USB thumbdrive’ on Google and then ordered 3 different brands from Ebay. This one by Sandisk was the best. All three worked, the differences are in the moulding, and the problem is how to attach them to your keyring (which you pretty much need to do so you don’t lose it!)
One had no connector at all. One had a plastic connector that you can put a string or wire through, but it was so small it snapped when I was tying the string to it.
Sandisk wins here. It has a tiny metal loop, you can just see it above – it’s silver. I wrapped some copper wire (red) through the loop and then to my keyring and twisted it (see above)
The thumbdrive is so small I hardly notice it’s there, but yet I always have it on me.
I’ve made a little script so that when I plug my thumbdrive into my mac it automatically syncs my dropbox to the thumbdrive, so I always have my latest dropbox with me on the keyring!
To buy one go to ebay and search for ‘Sandisk Cruzer FIT‘ they are around $10 to $20.
