I have two SO-DIMM sticks of a domestically produced Chinese brand named FASPEED, with chips bearing logos and markings that I don't recognize from anywhere else. These sticks' mfg. datestamp is "44-24" and from what I've learned they cost little in China but come with a salted price tag when sold through channels aimed at Western customers. I'm not sure if they come in fast-enough variants to compete, and not sure about the quality or longevity otherwise. FASPEED makes SSDs, too, but I have no data on those. I also have an M.2 SSD from another Chinese brand called XINCUU which I previously had never heard about. The label of that SSD is in parity with expectations of Chinese business morals - it claims to be PCIe NVMe with "1000 MB/s speed" but is in reality a SATA device, and it does not perform even close to the ~550 MB/s limit of SATA 3.0. Both of these run unusually warm for DDR4 memory and M.2 flash storage, leading me to believe they are wholly designed and produced in China.
