"Memory sticks are a great way to store data and applications for access on any computer you come across. With storage capacities already reaching 256 GB, today's USB sticks are often larger than yesterday's hard drives. Thanks to increased storage space and lowering prices, you can easy store nearly all your personal files on a tiny, go-anywhere USB memory stick. There's a downside to all that cheap, easy storage, though. It means there's even more data at risk should your USB stick be lost or stolen.
Luckily, it isn't hard to encrypt the data on your USB stick so that, should misfortune snatch it away from you, at least you can rest easy knowing that your data is secure."
