If for whatever reason you require hardware-encrypted portable storage this is an excellent option – no software required and works with any OS/device that supports USB 2.0 Mass Storage. Having used Ironkeys before – where you need to run on-board software to authenticate and access the encrypted storage – I can say that diskG* is much better – you can even boot from it and there is no risk of *any* software intercepting your access code as it is entered directly into the drive.
