Wow! This memory card is class. I use them in my HDR-CX900E. According to the manual only 64 GB cards have been tested, but it is also recognized without problems. Thus, I can record in Full HD with 25p whopping 17 hours. With 50p figure is still 7 hours.
Now I have not tested the card through its paces, but this specification has been designed especially for such a camcorder and it shows.
