Miniature key perfomance

I searched for a while a truly compact and powerful drive.
My happiness I have found is the Lexar Echo ZX, 16GB.
I use it for my car radio and once installed it is virtually not see, this will not stoke the desire of some thieves.
For transportation, no problem, it has a protective cover.
As for performance, no worries, when transferring MP3 files, I get to write the order flow from August to September Mbs.
Compared to other brands, it is simply the best.
