The Transcend SDXC UHS-I U3 64GB Memory Card with 64 GB for 30 is a bargain. For this, a speed that I (still) do not need. But the copy of the RAW images to the hard disk, the card reader is connected via SATA, I'm done faster. I have the same card registered with Transcend, 30 year warranty offered, so far has never been a manufacturer card failed. So I forgive like 5 star.
