If you work for highly classified government organization or corporate R&D center where document’s security is the top most priority then you would love the IronKey USB flash drive offering truly military-style security. It boast a hardware encryption chip that self-destroys after 10 incorrect password attempts, making the data of the drive totally unreadable. In addition it dual-encrypts your passwords with software and hardware encryption using different keys to prevent brute-force password guessing attacks. Or if someone tries to get physical (via power attacks, electron microscopes, etc.), it will self destruct in hardware.
Encased in rugged metal housing the IronKey is filled with an epoxy-based potting compound to seal all the components. So if an expert hacker tries to extract the data from the flash chips, he’ll almost certainly destroy the chips and connections inside, making further attack or disassembly useless. It’s now available in 1GB ($79), 2GB ($109), and 4GB ($149) capacities with 30mbps read and 20mbps write speed.
