M.2 (formerly known as NGFF) is a small form factor card and connector that supports applications such as Wi-Fi, WWAN, USB, PCIe & SATA, as defined in the PCI-SIG M.2 Specification (see www.pcisig.com).
- An M.2 card with a SATA interface will typically be an SSD, suitable for very thin devices such as Ultrabooks or tablets
- SATA M.2 is described in the SATA v3.2 Specification.
- Detailed M.2 specifications are contained in the PCI-SIG M.2 Specification (see www.pcisig.com)
- M.2 cards are available in single-sided or double-sided versions
M.2 - mSATA Comparison
Where mSATA took advantage of an existing form-factor and connector, M.2 has been designed to maximize the usage of the card space, while minimizing the footprint.
