unfortunately slow write speed

Map is described by Amazon with 90 MB / s read and 60MB / s write speed.
In fact, I have measured 87 MB / s read, but only 33 MB / s write speed.
The card is now writing a little slower than the Sandisk with 45MB / s (write speed 35 MB / s).
First sounds negligible.
In practice, however, unfortunately, that the Sandisk makes available your typing speed quite constant while the Transcend constantly breaks.
So however the speeds when writing 1,000 JPEGs via USB 3 in Sandisk 28-37 MB / s, at the Transcend fluctuate between 17 and 35 MB / s.
In the camera the speed for continuous shooting at Transcend breaks a little earlier than in a Sandisk (ie the buffer is used to, since it can not be emptied as fast). While the Sandisk then can still be photographed quite stable quickly, you realize when Transcend, as the distances between shots are shorter times longer times.
It thus confirms the impression from the writing test, that the write speeds vary greatly.

I can therefore only recommended for predominantly read-use, or in a slow compact camera the map.
(My tests were conducted in a Fujifilm Finepix performed X10, my clear writing power-hungry X100S I then no longer attempts)
