Certainly, this key does not have the best transfer rate with USB 2.0 as in 3.0. However, in view of its price, and its storage capacity, it is well worth the shot. The USB 3.0 transfer rate is more than enough to copy large files quickly without waiting.
Beware though, if you do not have USB 3 ports, better to choose a key with a better transfer rates, because I find it a bit slow USB 2.
