Hi, i just wanted to update this form on how my problem is being handled. I have contacted SanDisk Global Custome Care and was transfered to a Level 3 engineer who first asked all the same questions i provided to the online chat tech. He than blamed the slow speeds on the software i was using, (the software link was provided by SanDisk) and recomended increasing my test file size to 100mb and use Crystal Disk Mark. These test results were almost identical to the ones i got using the ATTO benchmark tool. Now he is blaming the results on mt usb 3.0 card reader, and is sending me a SanDisk card reader.This is all good but does not explane why my camera has extended buffer delays when shooting raw and jpeg files to cards 1 & 2. The supose speed of the SanDisk Extreme Pro cards is why i purchased them and much cheeper brands are preforming better in my camera :frowning:
