This is already my second SD10V Kingston, once in 8 GB and 16 GB in this now. The problem of the previous speaker with the low transfer rate I have not. Indicated a write speed of at least 10MB / s when I describe the card with my computer I reach approximately a speed of 11.5 MB / s, ie fits. The 16GB card I operate now in my Canon EOS 650D, and I have no problems there, images are quickly written by the camera into the memory, delete multiple images on the camera itself works fast and transferring the images from the camera to the computer is possible also at home in the expected speed. The 8 GB card I practice now for over half a year without any problems, the same, I hope now of the 16 GB version. If this is not the case, I'll mention the course here. For this price of me a strong buy recommendation!
