If you're looking for a fast, ultra-rugged, secure encrypted portable storage drive that's available in both HDD and SSD flavors, look no further than Apricorn's new Aegis Fortress ...
the Imation Micro HD
The Imation 4GB Micro Hard Drive's padlock design features a flexible USB connector that locks directly into the drive and can be used to clip the storage device to a belt loop or key chain. The hard disk drive is smaller in diameter than a quarter.
