Definition: A physical form factor for SSDs, describing the size and shape of the storage device.
Explanation
M.2 is a specification that defines the physical size and shape of a storage device, typically an SSD. It looks like a small stick of gum with memory chips mounted on a thin circuit board. One end slides into a connector on the motherboard, and the other end is secured with a screw. M.2 does not indicate the speed or communication protocol of the drive; it only describes its physical packaging.
Example
When you open a modern laptop or desktop, you might see an M.2 drive installed. It is a slim, rectangular device that fits into a dedicated slot on the motherboard, unlike traditional larger SSDs or hard drives.
Who This Is For
This term is useful for computer builders, IT professionals, and tech enthusiasts who want to understand the physical characteristics of storage devices and how they fit inside computers.
