That site / app is the second hand section of Taobao, some reseller selling the SSD not the manufacturer itself. The same can be said about the aliexpress listings. Like all things with buying from China, the risks are multiplied for overseas buyers, so I cannot say or recommend much, you do you.
10 layer board is supposedly also what Apple used, in theory it means a closer copy to the Apple original card is more likely than on the 4 layer board, which has to re-route traces perhaps with less careful considerations.
And FYI, WD has acquired SanDisk SSD division I think. SanDisk as an end product brand has a quite a bad rep in recent years, especially with how their portable SSD products failure and losing data, and yea your SD card experience is shared by many also. But as a NAND manufacturer / supplier they are fine.
