well one question before I answer below: your positive your motherboard has an M/2 connector on it for SSD?
the M.2 SSD will always be faster than a SATA drive, M.2 can runs up to 32GB/S where SATA can runs up to 6GB/S.
then you choice falls in that specific category, I would read reviews on M.2 Drives before making a decision, also pay attention to benchmark tests performed and compare them to each other. from my limited knowledge I would make my choice the Disco SSD Western Digital Black 256GB M.2 NVMe 2280 https://www.globaldata.pt/shop/western-digital/disco-ssd-western-digital-black-256gb-m-2-nvme-2280.html
