Decidedly USB sticks "Integral" are not surprising: excellent! After buying the Fusion key USB 3.0 32GB, I ordered USB 3.0 64GB mail. Upon connection, the contents of the key appears instantly! Not even need to look for it in the Explorer! The write speeds, especially in reading comply with USB 3.0. A mini reproach. Both the 32GB key is tiny, so the 64GB is more imposing size, but its lid fits, once the key connected, avoiding to lose. In both cases, I cling to necklaces badge holder, which allows me to remember them.
