At $159, the Apricorn Aegis Padlock isn't going to win any awards for its thriftiness, but when it comes to performance and features, our sister site, HardwareCentral gave it four out of five stars.

This hardware-encrypted drive -- with AES 128- or 256-bit encryption depending on the model purchased -- is small enough, at 3.3 by 4.7 by 0.8 inches, to fit in your coat pocket and secure enough to provide peace of mind should it become lost.

It comes in several models, some of which are less expensive. HardwareCentral reviewed the top-of-the-line 500GB drive with AES 256-bit encryption. Read the full review here.
