I just bought those two cards above. One 128 G series (for slot 1) and another 128MB M series (for slot 2).
I may sell my other cards now as I don't think I would ever used them.


Can slot 1 actually write at 300MB/s? Didn't see that in the manual when I looked.


No, slot 1 writes around 140-150 MB/sec best when UHS-II cards are used. The buffer in the camera is about 2 GB and it take about 14-15 secs to fully clear it after shooting the buffer full with RAW files. Seems to match A9 tests in cameramemoryspeed quite closely.

Here's a bit of math done to calculate/approximate the buffer size from an earlier thread
