From a capacity of 8 GB, finally ... 7.25 GB to be exact, this USB key as the previous version this a pretty cool look. However the speed of write transfers rotates between 3 and 5 MB / s. Not the fastest USB keys so. As long as you only use it for small office style files this will not pose a problem. By cons, if we begin to transfer large files you will need to take your troubles patiently, for it is far from winning the Olympics it!
