M.2 NVMe SSD vs SATA SSD
What is the difference between a Samsung NVMe™ M.2 SSD and a regular SSD?
NVMe™ SSDs leverage a new type of interface and protocol – Non-Volatile Memory Express – to break through the bottleneck limitations of SATA based systems. Concretely, this means that whereas SATA SSDs’ maximal performance does not exceed 550MB/s, NVMe™ SSDs can achieve transfer speeds of about 3,500MB/s when connected via PCIe Gen.3 x4 lanes.
