Reaches speeds of the stick under USB3.0, are:
195 MB / s sequential read,
95 MB / s sequential write.
Tests were carried out with CrystalDiskMark Windows 8. For those who want a bit more detailed values, I have uploaded a customer image. Under USB2 I have no accurate tests carried out, the maximum speeds should but read and write in the range of 30MB / s.
Shortly to housing:
The stick is relatively clunky. People where size is important, this should keep in mind. The stick is the size about the size of a standard lighter and has due to its metal housing, a relatively large weight so that it can stand out quite strong as Schlüssselanhänger.
Also can happen that the stick obscured to nearby ports because of its width.
Short Conclusion:
Super fast drive with USB3.0, which is visually appealing but somewhat clunky. I had to look and speed of the stick important and both criteria are fulfilled for me.
Therefore, strong buy recommendation!
