M.2 is a type of solid-state drive (SSD) that is used as an interface for storing data on a computer. It is similar to a traditional SATA-based SSD, but is smaller in size and has a more flexible form factor, allowing it to be mounted in different orientations and in more compact spaces. The M.2 interface supports both SATA and NVMe protocols, which provide high-speed data transfer rates and low latency.
M.2 drives are commonly used as boot drives in laptops and as storage upgrades in desktop computers. They are also popular in smaller form-factor devices such as ultrabooks and small form-factor PCs, where space is limited and the need for high-speed storage is a priority.
Overall, M.2 drives offer a convenient and high-performance storage solution for a variety of devices and computing needs.
