Some scam SSDs are smaller drives with hacked controller firmware that is bright enough to avoid detection with quick scans - you have to write beyond the real capacity then re-read to confirm corruption.
Note that I was warning about quick tests, I'll have to try “f3probe --destructive” on something next time I have some playtime to see whether I'd consider that quick! Of course, it could be much quicker than the full capacity write some tools use to find a defective or deceptive drive¹² but quicker and quick aren't the same.
If a quick test says the drive is fake then it is, and many fakes can be detected these ways, but it takes more to convincingly state a drive isn't fake.

[1] Only a little over true capacity should be needed for that, in the case where writes to anywhere up to capacity will work (which is common as creating a filesystem more complex than FAT/exFat often requires activity similar to what quick write/read heuristics do).
... unless/until the underlying flash fails. Which it probably will; there's every reason to expect these drives are made with the cheapest, worst flash available.
