I have this USB stick in addition to an already previously acquired S102 without "Pro" for some time now in use. In addition to the generally reliable operation I think especially worth highlighting that it has not only ordinary, the price reasonable and compared to its predecessor by even higher transfer rates of USB 3.0, but as has been the predecessor to USB 2.0 makes a very good figure, while other competitor surpasses that may be faster USB 3.0 though, but offer a more USB 2.0 only average performance.
This makes it a perfect choice for all those who want to use the stick on both interfaces or need, and can compromise on the highest transfer rates. As another drawback, I feel the lack of activity light that would show an after logging conveniently when you can remove the flash drive without risk of data loss. However, but I was ready to give it up in view of the low price.
