I have a high-capacity USB Stitch wanted to I can take anywhere in the world. The stick is stable and also very fast and looks good. Unfortunately I have only one USB 2.0 port but here are the values already really good. Allerdngs the values below USB 3.0 are much higher.
Write 26 MB / s Read 35MB / s
The only thing you should consider is that the stick is quite large, but that does not bother me personally.
