Flash storage keeps getting cheaper and cheaper. You can often find bargains on 32GB USB flash drives for $60 or less, and 4GB, 8GB, and 16GB sticks are far cheaper. But not all flash drives are created (or priced) equal. Some are faster than others, and some have other gimmicks, like password-protected file encryption.
Kingston recently launched a new DataTraveler Locker+ USB flash drive line that features 256-bit AES hardware encryption. Basically you can’t access the data on the sticks without a password. And you enter the wrong password 10 times, the card will automatically reformat the drive. That’s great if you accidentally lose the flash drive and don’t want your data leaking out to the world. But it also means you’d better be darn sure you remember the password.
The Kingston DataTraveler Locker+ USB flash drives range from 4GB to 32GB in size and run between $36 and about $154. They’re compatible with Windows, OS X, and Linux.
