M.2: Standards, Features & Form factors and keying

M.2 (pronounced "em-dot-two"), formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and connectors. It was developed to replace the older Mini SATA (mSATA) and Mini PCIe (mPCIe) standards.
