[XX='ehlcay1329, c: 874259, m: 1795385'][/XX] M.2 is a form factor. Mayroong M.2 SATA SSD at M.2 NVME SSD. So NVME at SATA lang ang may difference especially sa pinagsusuksukan.
Knowing na mabilis ang SATA SSD, mas maganda ang IOPS/Read and write ng NVME compared sa SATA. NVME r commonly 7x faster than SATA SSD and 35x faster than HDD (yep, that fast)
SATA up to 560MB/s read and write
NVME up to 4000MB/s read and write (depende sa progress ng NVME drives).
