What is the A77's actual/real speed for writing from Buffer to SD card?

That bottleneck is unplugged to a great degree with a UHS-1 90mbps or faster card in cameras capable of writting at UHS-1 speeds, i.e. a77/99.

The UHS bus technically supports up to 104 MB/s maximum bandwidth, does it mead A77/A99 can write over 100 MB/s? or maybe there is some other limiting factors here?

We need to find the real (not theoretical) speed for transferring data from Buffer to SD card to have a accurate answer to OP's question.

I can't find it in Soy documentations, or on the net, but if I'm not mistaking A77's can transfer at about 50 MB/s in reality. Anybody knows the exact speed for writing from Buffer to SD card?
