Is this card defective or am I using the wrong settings?

Had the same issue with Komputerbay 64GB 1000x. Solved by properly formating in a UDMA-7 capable reader (with USB 3.0). You can also try to low-level format inside the camera, might work.
If this doesn't work, I would assume you probably have a broken card.

Tried formatting multiple times, using both ExFAT and FAT32. Similar results each time. Low level format in camera doesn't help unfortunately. Strangely, in crystaldiskmark, the benchmark results are significantly higher, (read and write 65-70MB/s) but still not to spec. I suspect a compatibility issue with the controller is making the 5D3 not use UDMA 7 and instead some slower mode. In any case, it's going back!

I put it here ...
Found it via SLRlounge and the original blog post is linked:
https://blog.jeffcable.com/2012/06/why-you-should-not-put-sd-card-in-your.html

Maybe a1ex can give a word or two. Minor error: 5D3 works with 166x (theoretical) as in UHS-I SDR25 mode (AFAIK).

Don't know if it's worth the effort to comment his blog entry ...

Short answer: the two card slots are independent; there are two different controllers. The presence or speed of a SD/CF card does not affect the speed of the other card. You have bench.mo, feel free to prove me wrong ;)

Of course, if you enable the option to save each image to both cards (in Canon menu), the slowest card (SD) will be the bottleneck. That's expected.

Or, if you attempt to write to both cards at the same time, the memory bus appears to be the bottleneck. Can be worked around, to some extent, e.g. by disabling "unnecessary" LiveView image streams.

One more thing. Most of the time, this is a hardware limitation and can not be solved with a firmware upgrade.

It can (with sd_uhs), as the hardware appears to be the same as in other DIGIC 5 models. Maximum speed is still an open question, if you ask me, but further investigation will probably require a good logic analyzer, rather than "blind" trial and error.

No... I asked to the CPS of my city (Rome) and they told me they can't do the downgrade...

Applies to 5D3 1.2.3, too.
