SATA M.2 Card

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


  • 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


  • M.2 cards are available in single-sided or double-sided versions

SATA-IO, the SNIA Solid State Storage Initiative and the NVM Express Organization combined to host the webcast, "All About M.2 SSDs". The webcast provided a technical overview of M.2, including the following topics:

  • Recent trends in the M.2 SSD market
  • M.2 cards and connection schemes
  • NVM Express as it relates to M.2 SSDs
  • Throughput, latency, and IOPS performance of M.2 SSDs

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.
