SATA 3 vs NVMe (what is M.2?)

What is the different between SATA 3 vs NVMe?

• SATA 3 – An older protocol (can operate on IDE or AHCI)
• NVMe – A protocol that lets data be read and written via PCIe
• M.2 – Not a protocol but just a physical form factor (SATA M.2, NVMe M.2, etc…)

SATA 3 – Data cable and Power cable are needed to connect to the motherboard and SSD

NVMe – SSD to have its data read straight from a PCIe slot right on the motherboard, the drive draws power directly through the motherboard
