M.2, also known as Next Generation Form Factor (NGFF), is an internal storage device interface standard used to connect solid-state drives (SSDs), wireless network cards, Bluetooth modules, and other devices to a computer’s motherboard. The M.2 interface comes in various sizes and protocols to accommodate different devices and purposes.
Key features of the M.2 interface include:
- Versatility: The M.2 interface can support multiple functions, including storage, wireless communication (such as Wi-Fi and Bluetooth), and other expansion functionalities.
- Multiple Sizes: The M.2 interface comes in various physical sizes, ranging from smaller “2230” (22mm wide, 30mm long) to larger “22110” (22mm wide, 110mm long), catering to different device and space requirements.
- Various Protocols: The M.2 interface supports multiple protocols, such as SATA (for SATA SSDs), PCI Express (for NVMe SSDs and high-speed expansion cards), USB (for wireless modules and other peripheral devices), and more.
- Hot Swapping: M.2 interfaces often support hot swapping, meaning you can plug and unplug M.2 devices while the computer is running without the need for a shutdown.
- Reduced Cabling: Due to the direct connection of M.2 interfaces to the motherboard, there’s no need for data and power cables as required by traditional SATA or SAS connections. This helps reduce internal cable clutter.
- Flexibility: The diversity of M.2 interfaces allows users to choose devices of different sizes and protocols based on their needs and slot them into corresponding slots.
In summary, the M.2 interface is a modern and versatile internal storage device interface, suitable for various types of devices. It has become a common interface in many computers, laptops, and mobile devices.
