Flash memory drives, the size of your thumb, are dirt cheap and offer gigabytes of storage. It’s tempting to fill one of them with important computer files, clip it to a key chain and hit the road.
But what if you lose it while fumbling for change at Starbucks and the hacker in the corner finds it? This is not a good thing.
That’s where a new breed of flash drives comes in — chock full of military-strength encryption and passwords and keypad combinations that must be entered before the data can be accessed.

Setting up my 4-gigabyte, brushed-metal IronKey drive was pretty painless. After putting it in a USB slot on my home PC, I was asked to create a user name and password before I could access any of the storage space or other features.
