These numbers look reasonable for a low-end SSD that manufacturers throw into their laptops -- which is what your drive is, as far as I can tell. I can't find specs, but I suspect it is a QLC set with a small DRAM cache. I don't think you have a significant performance problem, but you are definitely feeling some pain -- so can you tell us more about what feels slow? Does it happen during the ordinary course of the day? -dsr-
