What type of connector is used for certain storage devices and is installed with screws on the left side?

The M.2 connector is specifically designed for connecting storage devices such as SSDs (Solid State Drives) directly to the motherboard. This connector type supports high-speed data transfer rates and is found in modern laptops and desktops because of its compact size and versatility.

The installation of M.2 drives typically involves aligning the drive at an angle and securing it with screws located on the left side, which helps to ensure a stable connection as well as preventing the drive from moving during use. This feature of being secured with screws distinguishes the M.2 connector from others that may not require such fastening for stability.

M.2 also supports various protocols, such as SATA and NVMe (Non-Volatile Memory Express), enhancing its flexibility in terms of performance and compatibility with different types of storage technology. Other connector types have different applications or mounting mechanisms; for instance, PCI Express connectors are used primarily for expansion cards rather than storage, while IDE connectors are largely outdated in modern systems.
