M.2 is a small form factor expansion slot that was introduced in 2013. It is designed to replace the mSATA standard, which was used for solid-state drives (SSDs). The M.2 specification was developed by the PCI-SIG (Peripheral Component Interconnect Special Interest Group), the same organization responsible for developing the PCI Express standard.

The first version of the M.2 specification, version 0.9, was released in September 2011. However, it wasn’t until April 2013 that the final version of the specification, version 1.0, was released. This is when M.2 slots started to appear on motherboards and other devices.
M.2 slots can support a variety of different types of devices, including SSDs, Wi-Fi cards, Bluetooth cards, and more. They come in different lengths and widths, depending on the specific device they are designed to accommodate.
One of the key advantages of M.2 slots over mSATA is their speed. M.2 slots can support PCIe (Peripheral Component Interconnect Express) and SATA (Serial ATA) interfaces, which allow for faster data transfer rates than mSATA.2 slots have become increasingly popular over the years due to their small size and fast speeds. They are now commonly found on motherboards for desktop computers as well as laptops and other mobile devices.
If you’re building a new computer or upgrading an old one, it’s worth considering whether an M.2 slot would be useful for your needs. With their fast speeds and small form factor, they can be a great addition to any system that requires fast data transfer rates or additional storage space.
In conclusion, M.2 slots were first introduced in 2013 with the release of version 1.0 of the specification by PCI-SIG organization after its development started in 2011. These slots offer faster data transfer rates than the older mSATA standard and are now commonly found on motherboards for desktop computers as well as laptops and other mobile devices.
