Not long ago there was someone here on UHH who had two UHS-II SD memory cards break. I think the dividers between the contacts broke. He attributed it to the extra row of contacts that UHS-II SD memory cards have. More of the card's outer shell is gone to accommodate the extra row of contacts. I can see how that would weaken the card's outer shell. SD cards are kind of flimsy to start with. I've been using one in my D500. I'm thinking about not using it and going back to UHS-I SD cards. My D500 still has the XQD card which is the main card anyway. What do UHH members think? Stop using UHS-II memory cards? Maybe the person who had the broken cards will be on this thread and can tell more about it.

For most of us, there is no advantage to the UHS-II cards. Few cameras have the extra row of contacts to take advantage of the higher speeds. Nor do our computers have them. All cameras can take them, but few take advantage.

That said, I have one because it was on a deep sale one day. I've had no issue. It works the same as my UHS-I cards.

I have some 32GB SanDisk Extreme Pro UHS-II memory cards (max speed 95MB/sec) that, at the moment, are working fine. I am always very careful when removing or inserting memory cards. That said, I recently bought 5 Lexar Pro 1000x UHS-II cards (max speed 150MB/sec) that I am trying out for some high volume (and video) shooting. They too are performing fine. I will let the forum members know if they fail early.

As other OPs have noted, most cameras can not utilize the extra speed of the UHS-ll SD cards. If your camera has two cards, said camera will only write to the slower card speed. I have a D500, and a Fuji X-T2, in which I use UHS-ll cards by SanDisk, and Lexar. I have never had any problem with them, but I tend to be careful when taking out or putting in any cards, since this can be a weak link, (bent pins in CF card slots). Use care with your SD cards, but unless you have the few cameras that can take advantage of the type ll cards, the type l card like Sandisk Extreme Pro, are quit fast at writing.

I had a divider break off. Actually one end popped off and I removed it the rest of the way to keep it from getting caught on something. No issue with it. In fact I forgot all about it until reading this.

From bent pins on CF and XQD cards, to breakage of double row SD cards? I bought my first 4gb SD card a decade ago. I own about 6 SD cards now. SanDisk and Lexar Brands. None of them are UHS-II though. If your camera is not compatible to that memory card. It really doesn't make sense, to pay the extra money to purchase one. I have never had any SD memory card break, or fail on me. So far. It is compatible to the Nikon D500, and other premium cameras.

Don't obsess. Like others, I've had dividers break off at one end, and I just pulled them off and drove on. Get plenty of cards, big if you shoot video, but wmaller for stills, unless you don't care if you lose a lot of ahots someday.

And if you are having trouble bending pins or damaging contacts on insertion/removal, perhaps you are too ham handed to own a camera. Is there a meaningful difference between taking .55 seconds and taking 1 second to remove and insert a card?
