M.2
M.2 is a specification for internally mounted computer expansion cards and associated connectors, primarily used for solid-state drives (SSDs) and Wi-Fi/Bluetooth cards. It replaces the older mSATA standard, offering higher speeds and more compact form factors through a small, flat connector that plugs directly into the motherboard. M.2 supports multiple interfaces like PCI Express (PCIe) and SATA, enabling fast data transfer for storage and networking components.
Developers should learn about M.2 when building or upgrading computers for high-performance applications, such as gaming, data analysis, or server environments, as it provides faster storage access compared to traditional SATA drives. It is essential for optimizing system boot times, application loading, and data-intensive tasks, and knowledge of M.2 helps in selecting compatible hardware and troubleshooting installation issues.
