LaCie has unveiled the CooKey and WhizKey, two new USB keys inspired by the award-winning iamaKey, both featuring the water- and scratch-resistant gold SIP connectors of their inspiration. The USB keys are available in sizes from 4GB to 32GB, and all include 4GB of online storage with LaCie's Wuala service.

Additional online storage can be purchased, starting at US$25/year for 10GB, but where things get interesting is that if your computer is turned on and connected to the internet for more than four hours a day, you can trade any unused local storage for the same amount of online storage.

If you're capable of putting two and two together, you'll have realized that this means Wuala is housing data on home computers around the world - but that doesn't mean your data isn't safe - it's encrypted using 128-bit AES encryption, and stored redundantly in several locations to speed up transfers.

The CooKey and WhizKey are available for US$19.99 for 4GB, $29.99 for 8GB, $54.99 for 16GB and $99.99 for 32GB.
