DreamWare Computers posted a review on the InWin Ammo 2.5" SATA HDD Enclosure

With the prices of portable hard drives and USB flash drives continually dropping, the abundance of these devices in the hands of consumers is ever growing. There's no doubt that the portability of these devices is excellent, but what do you do when you forget where you left that portable storage device full of your personal, and sometimes confidential data? If you look hard enough, it's not hard to find several models of USB drives and hard drive enclosures that go the extra mile for your safety by encrypting the data they contain. The Ammo is the latest 2.5" drive enclosure to come from InWin. This high quality drive enclosure encrypts all the data contained on the drive, decrypting it only when the appropriate RFID tag is swiped over the sensor on the case. To keep the drive physically protected, it is internally encapsulated in a thick, drop-proof and waterproof rubber skin.
