The presentation in the photo does not match the product delivered by POPP in the form other than the color. That part has 64GB capacity. I never take the trouble the device speed with not efficient for me Industry to try test methods - here my result for the "perceived" performance - on my MacBook Pro's part is not faster than my two year old Corsair sticks - but what a eighth performance of POP sticks are described - in German quickly is different. I do not know where the manufacturer's test data takes her - not with me funktionierst. Since I use certain Sticks day I have an idea of ​​resilience and quality - which has this stick now times not - Low to wobbly plastic case - as any CF II card robust. A return would again cost cause so I decided to use the stick as a backup solution behind my television because he is not stressed mechanically and it sees him not :-) - I would not buy this part again.
