Especially with the uncompressed 14 Bit Raws, People now run into this - without thinking and just because they wish to do best quality.

As someone on a FB Sony group wrote: he had problems to shoot a wedding with uncompressed Raws, as the buffer filled too fast and he missed a lot of shots....... (about like that)

well the files are nearly twice the size, and Sony probably never built the data channel in the camera to be much faster than an optimized USB2.0 internally........ yup.

read it here in Details - that is a tremendous piece of work by Alik Griffin.

I just want to thank you once more for this info. I ordered two cards last week, which were delivered today and this link was a big reference : with peace of mind I could chose a Sandisk Extreme Pro class I and thus spare quite a lot, since class II apparently doesn't improve the writing speed of the Sony body, while costing twice as much.
