Performance: Top - quality: Meeh

First Impression:
The USB stick is with his 7 cm not exactly small, but nice and light and handy. It is possible to carry this stick on a key chain, as an eyelet on the rear part is available - I personally find him for it is too large and the plastic does not make the best impression of all. Currently, the Stick has been only a few times in use and I can only guess that show with increasing use noticeable wear. Also, the slider could not cope with the load. Here I will post new information after a given time.

Speed:
Otherwise, you can speculation outside off what I'm doing here in the assessment, then you get a pretty good USB stick.
exFAT: Read 251.3 MB / s - Write 95.7 MB / s
Mac OS Extended (Journaled): read 253.6 MB / s - Write 94.4 MB / s
Tested with a 5GB file on a MacBook Pro with Blackmagic Disk Speed ​​in a USB 3.0 port.

Conclusion:
The capacity of the USB stick are really good and it is always gratifying to use it. Only the mechanical component can be a problem. Since the production quality is not the best of all. For about 30 performance is superficial and that is good, but I would like to see more quality of the product. At 55 RRP I would not buy the stick!
