Despite claiming to be 170 MB/s card, it actually performs at about 65. I tested both cards on 2 usb 3.

I was originally going to just get the Extreme, but when the Extreme PRO goes down to a lower price than the former you haven't really got anything to lose! I bought two SanDisk Extreme PRO 64GB SDXC Memory Card up to 170MB/s, Class 10, U3, V30 primarily for my Panasonic Lumix Mirrorless Camera DC-G9 and I've had no issues whatsoever. So I formatted it and re-run the test with "fakeflashtest" and it passed with flying colour's, I then ran it with crystal disc and you can see by the image it is as fast as stated. Ideally you need to match the card to the capabilities of your device, for example putting a slow card into a very fast device will mean that everything is very slow.
