Which tool to recognize type of USB-stick 1/2 TB

As i told in PC Deals and Steals i had a fraud with a non SSD-m1-NVMe-stick. both 1 and 2 TB.
They cannot be SSD since speed is half of what Sata III-counterpart is delivering.

Is there a tool to test fake-sticks? Thanks
Update:
this one should help

H2testw running is taking forever! and filling 1TB data too.
