All things considered, I was impressed with the Kingston DataTraveler BlackBox. It performed admirably well even though it has to deal with on-the-fly 256-bit AES encryption. Also, the security process is relatively transparent in that all you have to do is put in your password and subsequently, the drive acts just like a normal USB flash drive. The build quality is excellent unlike some older DataTravelers I've owned; I soaked the drive in a cup of water for several minutes and it still worked.
