Like I said there are many options, although the IronKey is CESG CAPS approved, so is good for here in the UK Government use. Dont get me wrong I am not saying the Government do everything right, but it does undergo some scrutiny.

They actually say "the world's most secure flash drive". I suppose if you include the additional security measures that they have implemented, in addition to the method of encryption, this could be the case. If we're going to give a product the beat down for marketing hyperbole, then MXI should be included for saying things like "the ultimate safeguard for your most critical assets"

Are you sure IronKey is CESG CAPS? I dont see it anywhere on their site.. http://www.cesg.gov.uk/find_a/caps/index.cfm

(I did notice the Memory Experts International drive however)

Ironkey has a whole list o' features here:

Including (sparse) details on their various security measures.

I don't use, endorse, or rub my junk on either of them. My point is, that if you're going to bag on one company for saying "the world's most secure flash drive" which translates to "we're the best", then you should also apply that to another company saying "the ultimate safeguard for your most critical assets" which also translates to "we're the best". Now if you want to compare apples to apples, such as the strength of their AES implementation, that's another story, but lets leave the marketing messages out of it.
