How these two compare
Sequential throughput
fanxiang S690Q 1TB is rated 4800 MB/s read and 2900 MB/s write; Western Digital WD Green SN3000 1TB, 5000 MB/s read and 4200 MB/s write. These are peak sequential rates over PCIe — the speed you would see copying one large file. For boot, app launches and everyday feel, random access matters more than this headline figure.
NAND and warranty
NAND: fanxiang S690Q 1TB uses QLC and Western Digital WD Green SN3000 1TB uses QLC. The tier is bits per cell — SLC, MLC, TLC and QLC from one to four — trading density against endurance and sustained-write speed: QLC is cheapest per gigabyte, TLC the mainstream balance, and the denser the cell the sooner sustained writes taper. 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.
Which to buy
With a price missing for at least one side, there is no cost verdict to give. What separates two otherwise-similar drives is up in the sections above — sustained and random behaviour, whether there is a DRAM cache, the flash tier and the warranty — so weigh those against what your build needs.
