It’s pretty simple really: Kingston makes good flash-memory USB drives. Kingston takes said drives, encases them in titanium-coated stainless steel making them waterproof to depths up to four feet and protects the data on the drives with 256-bit Advanced Encryption Standard (AES) hardware-based encryption that can be encrypted and decrypted by authorized users only, without the need for any additional software. The Privacy Edition ups that security by including a complex password protocol for locking out potential attacks after ten failed password attempts. The DataTraveler Secure is available now in 512MB ($33), 1GB ($62), 2GB ($108), and 4GB ($244) sizes; the Privacy Edition will show up in January 2007.
