Possibly, the most stylish USB memory stick I’ve come across, the NAT has chrome surrounds (although this is a painted Chrome finish) and padded leather inserts on both large sides. But the trick up the sleeve of this is that this can restrict copying, or more, of data on it.

Okay, let’s finish off with those looks. At the rear end is a swivelling ring, to make it easy to add this to a key-ring. On the other side is a cap, covering the USB plug. However, this can’t be stored anywhere else on the device so may get easily lost. Oh, and the leather is available in both black and brown. Storage sizes range from 4GB to 32GB and prices from £15.99 to £39.99.

So, you plug it in and you see what appears to be a CD. Click on it and a small .exe file is all that’s present. Your computer stats will show the drive to be quite tiny in size. Run the .exe and it will launch the NAT software. The first time you use it, it will ask you to set a password. After that a padlock icon appears in the corner of the screen (which can be moved about if it gets in your way) and can be used to lock and unlock the rest of the USB drive – once unlocked it will appear under My Computer in its full, accessible size.

The way it works is that certain types of files – images, videos, PDF and eBooks – when added to the drive will then be converted into a new format. With the software active, whether the contents are locked or unlocked, it will display them. Copy the files elsewhere and you’ll find they can’t be viewed. The only way to convert the files back to their original format is to unlock the drive using the aforementioned password. As well as this there are further options to limit the number of times the documents can be viewed, expiry dates and, even, an additional password that must be entered just to read the documents in the first place.

Now, one thing that’s not mentioned is whether this is USB 2 or USB 3. From the benchmarks I’d certainly say this is the former. A sequential read speed of 19.4 MB/s and random read speeds of 5.5 – 20.4 MB/s are quite average. Sequential write speeds of 14.4 MB/s and random write speeds of 0.007 – 0.715 are, on the other hand, less the average.

Sadly, compatibility is Windows only but I tested in under Windows 7 and the latest build of Windows 10 and both worked great. Well, okay, that’s not quite true. On my wife’s Windows 10 laptop it worked fine. On my desktop, on the other hand, it told me I had an incompatible OS. Yet, both are fully up-to-date. The only difference, that I’m aware of, is that one is an OEM version and the other (my desktop) is one of the free upgrades from Windows 7. But, this is something to be aware of.

The packaging consists on a stylish box, with the key set, inside, in a foam layer. Instructions are underneath the foam (which is something I missed at first!). It looks nice but very environmentally friendly at all.

It have a need to restrict copying of certain types of files (and that is a limitation, as it is only certain types) then I can’t imagine a better way. For most people, though, this kind of device won’t be needed. But it looks great and is very easy to use.  But, yeah, it’s pricey (over 10 times the cost of a “standard” 32GB USB 2 memory stick) and not particularly quick.

Maybe, with all their “leaks” this device is the future for Oscar voting 😉
