M.2

M.2 is a connection type specification for computer expansion cards, introduced in 2014. The two major types of M.2 devices are the SATA M.2 and the significantly faster (and more expensive) PCIe M.2.

M.2 is used for storage devices, such as SSDs, and high-performance non-volatile memory storage, such as Intel Optane.

Other M.2 devices

Other devices that are not storage devices that support the M.2 standard include:

• Bluetooth
• NFC (near-field communication)
• Satellite navigation
• Wi-Fi
