the packaging looks at first glance like a blister, but is made of cardboard with an insert made of transparent plastic, so relatively injury Neutral.
For the Function / speed test in the laptop I used the supplied adapter to standard SD size (for Intressenten: he also has this lock slider on the side can be seen not good on the product image..) In which the map Unfortunately, very difficult to shove lies. The extract of the map is the real test of patience. But good, better than if she were to loose ...
The transfer rates are noisy "h2testw (of Heise.de)" Neat:
Letter: 5,42MB / s
Read: 18,9MB / s
However, the card is their existence not limits in the laptop, so herausfuddeln again and got so into HTC Flyer tablet, where right is pending a further test with "SD Tools (of Veluscek Ales)":
Write: 5.1MB / s
Read: 21,0MB / s
And since all good things are three known: "AnTuTu benchmark (of AnTuTu)" may also let off steam:
Write: 5.2MB / s
Read: 15.1MB / s
So really clean speeds for a Class 4 card. Is of course to note that can only be achieved with very large files these values. (Eg archives) Small files (photos / music files) take longer naturally.
A star deduction there yet for the unwilling adapter. (A half one can not pull off.)
