PRO
1. Fast SSD with real-time encryption in hardware, no noticeable delay in the data transfer, but not very fast in a flash
2. relatively small housing, relatively easy
3. Operation is simple
4. Good use touch panel responds to pressure
5. energy consumption low but not quite perfect (more on that below CONTRA)
6. Stable little storage case
CONTRA
1. Touch the box leaves footprints, so you can see which keys are used and which are not
2. 8 digits long though (makes sense, however, the system could also accept 4 and the remaining 4 itself "internally" Generate Security code must be
3. Data connection not entirely reliable when USB cable is too long, SSD is suddenly no longer recognized
4. Touch screen is a nice gimmick but right buttons would make more sense and less prone to fingerprints
5. An integrated USB cable would be desirable, because you always have to carry around a cable and in the storage case is not a place for the cable
Conclusion: System seems matured, but you have to be aware that without the two enclosed smart card Nothing beats. One should have in your pocket, transport for safety reasons, of course, in the protective cover of the SSD and the second smart card should be kept in a safe place in case you lose the first smart card. Clean from her building, the security seems to be very high but I would still be careful with sensitive data and this may for example again: encrypt with TrueCrypt on the SSD.
I have the SSD with OSX Extended Journaled format, it works just fine.
The price is steep though but if the security concept works, it is certainly not too expensive.
