While it might look like it has 2 TB, if you try to actually transfer anything more than a couple gigs onto it will corrupt the files and make them unreadable. If you want something that has a lot of storage in the same small size, I’d recommend this SanDisk on Amazon. I’ve used it myself and it is legit
If you don’t already own the microSD, a 512gb USB stick is probably faster and cheaper. But I think you’ll struggle to fill it. SanDisk does the mini one, it gets toasty but it has a 5 year warranty https://www.amazon.com/SanDisk-512GB-Ultra-Flash-Drive/dp/B083ZS4HYD
The Samsung sticks can reach faster speeds, I’d look at what others have tested the speeds on
I would strongly, strongly advise against putting a MicroSD card that big in your Pi. If it goes (Which MicroSD cards tend to go sooner than any other storage medium), you then have to rebuild everything unless you're content to keep a whole ass 512gb image backup up on your computer (And then rebuild from that, which would take hours upon hours).
Instead, I'd recommend getting a large thumb drive. I use SanDisk's UltraFit line in my RP4:

Under $50 and you can just plug it right into any USB port on your Pi. Aside from the piece of mind of knowing your entire system isn't fucked if it goes (Backing up a 16gb MicroSD is much quicker for recovery), it's also a whole lot easier to load games up on, since you just need to shut down, pop it out, and pop it into a computer (Faster than pulling out a MicroSD or going over network).
SanDisk has one now too. I typically trust SanDisk more than PNY but the reviews on this one are not that great (and it is cheaper too). Personally I'm waiting to see if Samsung will have one soon.

That’s a great idea! I am using this and it’s perfect!

The unit with that USB plugged in fit PERFECTLY in a Pelican 1040 micro case!!
