In general (not just with drones), I've never had any problems with the Sandisk Extreme Pro cards, nor with Lexar Professional, nor Samsung Pro Plus, nor any other manufacturer's best cards. I think the top tier of most well-known manufacturers' lines are probably pretty safe.
But there's definitely a difference on the second tier. I have a high-end, dual lens dash cam that can be brutal on SD cards at its highest settings (both lenses at 1080 / 30 and ~ 20Mbps bitrate). With complex scenery, it'll start losing frames and/or reducing the bitrate using anything other than the best-quality cards. I think it's the heat that pushes lesser cards over the edge.
I may have some very nice test footage taken with that dash cam somewhere. The footage I uploaded a few years ago was removed for copyright violations because I had the car radio on and was singing along with the music. I have to check whether I still have the originals just for SD card comparison purposes.
On a more practical level, the high quality did help me in an insurance claim when a dump truck in front of me starting projectile-vomiting rocks from the hopper. I was able to read the plate at quite some distance to identify the operator, as well as prove that I wasn't speeding nor tailgating. That was with a Lexar Pro card.
One thing I noticed early on with this drone is that it warns you when the card is struggling. The message is something like "the SD card is writing slowly." I had that happen when I was doing the original 4K / 60 test footage with a Sandisk Extreme (not Extreme Pro) card. That's a handy feature.
I have a similar dashcam setup, its a single dashcam that records in 4K; not sure of the data rate but it has to operate every day after sitting in the car's 130+ internal temps. In this day and age I think every single driver should buy and install one for every car they own. These days if its not on camera its very hard to prove guilt or innocence. I don't even know what card is in it (I think its a Lexar), it came with a 32GB microSD card and its worked fine ever since. Dashcams are another area where its important to get a reliable one that can work without issues and mainly that can withstand the heat of sitting in a car in direct sunlight for hours at a time. There's no point in buying a dashcam that fails the one time you really need the footage.
I read somewhere that there are really only two SD and microSD card manufacturers, Lexar and SanDisk. Anything branded anything else is a rebranded Lexar....not sure how true that is. In most reliability tests I've seen SanDisk consistently slightly edged out Lexar so years ago I decided to standardize on SanDisk for all of my memory card needs.
That is good to know that the EVO II will warn you when there are write performance issues; its better to find out that way then after a day's footage has been lost.
I need the dual cams because where I live, the population roughly doubles in the summer; and the downstate folks have a habit of tailgating. It's [usually] not aggressive driving. It's just that the three-second rule is a fantasy in the NYC Metro Area. If you allow three seconds of distance, three cars will pull in front of you. They bring that habit with them.
The problem is that the deer around here must be chronically depressed because they keep trying to end it all by leaping in front of moving vehicles. So if I have to stop short to avoid a deer and get rear-ended in the process, I want both the deer (to establish the reason) and the guy who rear-ended me (to establish who was at fault) to give to USAA.
I suspect Samsung is a primary SD card manufacturer, as well. They certainly have the capability.
Anyone looking at cards, I will suggest one further point... rather than picking up one larger capacity card (i.e. 256Gg), grab two smaller (i.e. 64Gb) capacity cards from the same tier/manufacturer (providing specs remain consistant).
If you are following recommended processes and reformatting before each day's flying, you'll likely never fully utilize that higher capacity. As well, having 2 twin cards automatically provides backup in case of card failure, theft, ect. Same investment, more wide ranging protections. YMMV.

Apologies if this has been asked and answered already... Can I test the speeds of the card on my computer?don't forget to test your card before putting it to work!

I had the drone complain about a Samsung Extreme (not Pro) card a few times. The app kept telling me that the card was writing slowly, or some such thing. I went shopping for new cards and found the PNY's on sale at Wally World, so I bought two. I'm still using them. I've bought two more since.thanks for the update, I also mostly shoot continuously and it's about half 4k and half 6k and I use various microsd cards from pny to samsung, sandisk to generic. unlike other cameras, the evo2 doesn't seem to be picky about the media. I haven't really experienced cards that won't format correctly or videos that end up corrupted. I almost never use the internal memory space and I copy off all media from the card after every session and then reformat the card in the drone just before the start of the next session.
