What module is typically used for connecting high-speed storage devices in modern computers?

The M.2 slot is specifically designed for connecting high-speed storage devices, such as solid-state drives (SSDs) and other expansion cards. This interface offers a faster data transfer rate than traditional connectors and is compact, allowing for more efficient use of space on a motherboard. M.2 can support various protocols, including NVMe, which takes advantage of the PCIe interface to provide significantly higher speeds compared to older storage connection methods.

While the PCIe slot is also associated with high-speed connections, it is broader and used for various expansion cards, including graphics cards and network cards, rather than being dedicated solely to storage. IDE connectors are outdated and designed for older hard drives and optical drives, making them unsuitable for modern high-speed storage requirements. USB ports, while versatile for connecting numerous devices, do not match the data transfer capabilities of M.2 connections for storage applications.
