Cheap and nasty

Was just in the zoo and it sucks!
Canon EOS 7D, cheetah enclosure: 15-17 photos (RAW 8B / s) just before the catch of prey - Busy - Memory Card stores.
Have a Transcend 16GB 90MB / s - unfortunately was just full.
and Kingston 600x - about the same rate, I thought at least.

Both have a theoretical capacity of 90 MB / s
Transcend after about 20 images of 8 frames / sec to 4 B / s
Kingston night almost 20 pictures 0 B / s for a few seconds (felt a few minutes) after one or two frames per second

Benchmark: Transcend 88 MB / s when reading
Kingston 42 MB / s when reading

I still have a Sandisk theoretically reads with 60MB / s, this is however felt faster than Kingston.
Always thought Kingston plays in the Oberliega, but had to let me convince you otherwise: - ((

However, price / performance, I find quite okay at the map, at other firms costing easily twice.
