512GB cards are perfect if you want to keep weeks of imagery on a card without having to change it.
Completely agree. I use super fast 32GB to 128GB (if I'm doing lots of 4K Video). Remove them/upload content to computer after every flight/job. Format them in my Mavic 3 before using again. Seems to work well for me.
For sure, make sure your equipment is compatible; most newer stuff will work.
So far so good, just remember to check each card individually after you get them. It's a simple, quick and easy test to see if it is counterfeit.

Thanks. The tests seem to be just confirming the storage capacity, which can be overstated in fakes.How to Spot a Fake MicroSD Card and Avoid Being Scammed
How to Spot a Fake MicroSD Card and Avoid Being Scammed
Fake microSD cards have misleading high storage capacities. Don't be fooled! Here's how to spot a fake microSD card.
I do a "the proof is in the pudding" test. I copy 256GB worth of checksummed files (or whatever the card's capacity is) to the card and then verify the checksums right from the memory card. If the card can store that much data and read it back without error then it's doing its job.
I'm not the microSD card expert but I believe the storage capacity is the main concern because it isn't easy to check until it's too late. Anyone should be able to check the speed on how fast you can write and copy files to and from the card, there are all kinds of checkers and you can often eyeball the difference. I don't suppose there is any value to a counterfeiter to provide a card which has all the promised storage capacity yet not the r/w speeds if that is even possible, at least for the larger cards. I know speed is a concern so when you are checking capacity, use this software to get an idea about speed as well: H2TestW- Download - Official Site [2023]
The problem is a good counterfeit card will report fake data and it may appear the files are reporting correctly when they are not. You end up with files on the card but everything appears to be good, but they aren't. That's the big gotcha for people who don't know what to look for. Maybe I didn't get your point about checksums so this might be the same thing: I recommend this software: H2TestW- Download - Official Site [2023]
This is exactly why you write checksummed files to the card and then read them back to verify the checksums. That way you know that 256 (or whatever) GB was written and 256GB was correctly read back again. The only way a card can do that is if it has 256GB to store all the data, otherwise you wouldn't get matching checksums.
Yep for sure but my old school computer skills have long since become rusty (and I wouldn't know how to do that anymore) and I let sw like h2testw do it for me. I would be afraid of getting a checksum error on a non-counterfeit card and not know for sure why....
