You'll either love or hate the design of the ATVs, depending on how much you like the feel of rubber. Rubberized casings are all the rage, in a range of products where differentiation is now the key.

The boast of a 100 per cent waterproof casing seems to stand the dip-in-a-bottle-of-water-and-shake test, and the read/write speeds are pretty impressive too.

If you're after a storage device to look after the most valuable of files while you climb mountains or head off gorge-walking then the ATV is for you. It's on the pricey side, but it still manages to outperform most of its price/capacity contemporaries.
