FZ150 card write speed and 1080/60p video

It's been discussed on another thread that the FZ150 apparently does not support UHS-1 (cards) which seems to negatively affect the burst write speed. I am curious as to how this affects the camera's ability to capture video at 1080/60p running at 28 mbps. Does it down sample in the camera when writing to the card or are there any dropouts on playback (in demanding scenes where also the buffer is limited) .....any recommendations as to which card to use especially for 1080/60p video?

Thanks P
