Fastest Cards in the market
Ignore the review claiming the speeds are not as advertised. You need a proper reader to take advantage of the speeds. The one the other reviewer is not capable of taking advantage of the extra connectors on this SD card for full speed. Review: For those of you that love saving time at every step of a professional work flow, these cards are amazing. I use them with the Sony A9 to take advantage of its full potential.
Fast Read! But Writing is less accurate
I love the card. I honestly have not yet been able to try it in my Sony camera because it has not arrived. Using my iMac Pro and the built in SDXC UHS-II slot, I recorded a max write speed at 82 MBs, and read at 225 MBs using black magic disk speed Mac App. Yes the speeds are great compared to original SD cards, however if Sony is going to label the read and write speeds as something they are not, it becomes mis leading.
