What type of storage device plugs directly into a connector on the system board?

The M.2 Solid State Drive is specifically designed to plug directly into a connector on the system board, making it a unique type of storage device. Unlike traditional hard drives or external storage solutions, M.2 drives are compact and use a dedicated interface made for high-speed data transfer, which allows them to integrate seamlessly with the motherboard for enhanced performance and reduced latency.

M.2 connectors are soldered directly onto the motherboard, or they may allow for a removable drive that fits into a dedicated slot. This direct connection contributes to the overall efficiency of data access and system responsiveness, which is a significant advantage over other storage options that rely on external cables or enclosures.

The other options involve different methods of connection. A 2.5-inch hard drive typically connects via SATA, which uses cables to interface with the system board. USB flash drives connect through USB ports, which are external to the motherboard and not plugged directly into the board itself. Similarly, external hard drives connect via USB or other external interfaces and are separate from the motherboard, demonstrating the distinct nature of the M.2 drive's design and functionality.
