NAND and warranty
NAND: fanxiang S690Q 1TB uses QLC and Western Digital WD Green SN3000 1TB uses QLC.

On the cover: fanxiang S690Q 1TB does not state one, Western Digital WD Green SN3000 1TB carries a 3-year warranty. The length is the maker's own vote of confidence, and on an SSD it tends to track the endurance rating — a longer warranty usually meaning more rated writes.
