Addendum on 02/10/2014 at the suggestion of Felix Werner:
Have checked with h2testw (write 500MB and read).
Result: Writing with 9,67MByte / s, reading 27,4MByte / s
For my purposes perfectly adequate, since I nich constantly need to copy new data.
A small point of criticism:
On the black plastic protective cover for the micro-USB connector for Smartphone Connection
as well as the metal housing with a small plastic nose hole.
They're certainly thought that you can run through a cord dur Both so that the cap will not get lost.
It would be nice if the manufacturer could spendieren as adding a matching string with metal screw.
For the price of the stick about this 5-cent-addition would have to lie in it.
