My budget function, despite this key corresponds to what I was looking for. Fast data transfer, even if comparing it with other more rapid key, it is somewhat disappointed. Now, compared to some other key, if the difference is sometimes in seconds ... which to transfer a large file is admissible, the price still function. Ability to encrypt the data (if useful) and safe (password not to forget ...) is useful if you want to protect certain files (eg loan of the key). If you are looking for speed, look elsewhere. If the speed is not a priority, it is a good buy.
