So,
A: = No
B: = Yes
What I was after are they in your opinion defective when new?
About a 2 years ago, it was brought to my attention that SD cards do fail in time / usage same as SSD drives.
If anybody has any info on my statement: "SD cards do fail in usage" Please reply!

Hey doods;
I have TWO of these SanDisk Extreme Pro 128GB MicroSD cards that I use in both my P4P AND my Hero7 camera. I seem to have problems with both cards in BOTH devices. Seems the 128GB cards are the common denominator. Either recording stops completely and erratically, or the bitrate gets throttled down to 2/3 what it should be.
Here's a screen capture of a shoot I did today. The bird randomly stopped recording 4 times. And you'll also notice - despite equal length files - the file sizes vary greatly. This is due to a lowered bitrate that happened quite randomly.

Notice these two files of greatly different size, but almost equal in length.

Anybody else having problems with these cards?

I just picked up a pair of 128GB Lexar cards from Amazon, but they don't seem to be living up their claims. Despite claims of 270MB/s read and 150MB/s write, benchmark tests are closer to 80MB/s:

I reached out to Lexar to confirm that these are genuine Lexar cards, but I'm pretty sure they are, as counterfeit MicroSD cards rarely break the 20MB/s benchmark.
In real-world write tests, the Lexar did even worse.

Worth noting, these benchmarks are actually SLOWER than the SanDisk 128GB:

These tests were conducted on my video editing machine (which is a monster) via the USB 3.0 port via a Transcend USB 3.0 card reader.
What kind of benchmarks are you seeing with your Lexar cards?
UPDATE: It seems that in order to achieve full read/write speeds, one must have a DEVICE that supports the new UHS II standard. Neither my GoPro Hero7 Black camera nor my Phantom 4 Pro support these standards. Maddening. So today I'm going to simply try recording for hours in both devices to test reliability of the new Lexar cards.

I use SanDisk Extreme Pro 65GB almost exclusively in my P3A but I use a 128GB in my Hero7 for about 6 months now with no problems. The thing gets VERY hot mounted to the inside of my windshield driving through the Nevada desert in the summer.
I saw this kind of thing when I bought a Samsung EVO 128GB but the problem there was it only stored 16GB. FAKE! After some research, sure enough, it was a fake.
Don't know if that (counterfeit) is your problem or not.
Thanks for posting this. I currently use both of these - one hasn't been in use for a while which I'll be using inside the Mav Mini next year, the other in my P4P. I'll do some tests and report back here if any issues.
have you tried contactign Sandisk?
Don't they offer something like a lifetime warranty or am I making that up?

interesting info, as I just put a Scandisk extreme 128gig card in my M2P, put I have yet to take it out.
all of my other drones have Scandisk extreme 64 gig, my MP has a scandisk Extreme Pro 64gig.
haven't had an issue yet from any of my cards.
I wonder if the transfer speed could be an issue with the drones? I've only read that 64 gig are the normal max, but many have used 128 gig without any issues.

Good deal. I'll be interested to see your results.

I think the warranty for the Extreme Pro cards is like 10 years, but it might be lifetime.
...
Regarding the P4P issues, I still have to test the new Nexus card in that one. I'll do that in the next couple days.
