Corsair Mini Voyager 4GB

Although we have seen slightly smaller flash drives than this, all have sacrificed a certain amount of durability for compactness.

This one, though, has a soft rubberised coating, which should protect it from knocks and bumps, and the USB plug can even be retracted to protect itself when in a pocket or bag.

And should the weather take a turn for the worse when you pull it out, it's water resistant, too.

It's also Tardis-like: small on the outside, but extremely capacious on the inside - the 4GB storage is enough to carry thousands of photos, about 1,000 MP3s or even a few movies.

Considering the storage capacity, and the tiny size, £18 is a remarkably reasonable price and on a par with other, much less pocketable drives.
