What do you think is in a USB stick? Here:

Kingston 1TB flash drive: https://www.amazon.com/dp/B09DVQ32XQ

Samsung 1TB SSD: https://www.amazon.com/SAMSUNG-Portable-SSD-1TB-MU-PC1T0T/dp/B0874XN4D8/

Same size, same speed. They even use the same NAND flash memory.

What, exactly, is the difference between these two products that makes one good and one "crap"?
