The speed is kind of a red herring. The defining characteristic of fake drives is that they have less than the advertised capacity, but have a hacked firmware that misreports their capacity to the system, and fails when more than the actual capacity is written. So to find out whether a drive is fake, you have to fill it all the way and read the data back.

Counterfeit mainly just means it's pretending to be something that it isn't. It's entirely possible this drive has the advertised capacity (though I wouldn't count on it), but it would still be a fake.

No, it isn't the advertised capacity, because counterfeiting scams require a large ratio between the value of the part claimed and the part provided, and you can't get 2TB of flash memory chips cheaply no matter how slow you're willing to accept. When counterfeit storage devices like this are disassembled, usually they're found to have a small microSD card in them.

I thought this was only common on fake flash drives and external SSDs? Has this been happening to NVMe SSDs as well? It's definitely possible, but scammers tend to be lazy to branch out beyond what already works, and SSDs are a bit more complex.
