The memory capacity is by appointment and after several months of use it resistant to multiple writes / rewrites. I do not have a USB 3.0 port on the computer judging the transfer speed .... The aluminum casing is susceptible to scratches and its thinness makes it sensitive, at its end, deformations (due to the bad I made a experience also useful protective cap against dirt). The triangular shape "design" for the key ring, weakens the attachment, shame!
