Storage interfaces are the methods and protocols that allow computers to communicate with storage devices, such as hard drives and solid-state drives. They define how data is transferred between the storage device and the computer's system, ensuring that information can be read and written efficiently. Common storage interfaces include SATA, SAS, and NVMe. These interfaces vary in speed, performance, and compatibility. For example, NVMe is designed for high-speed data transfer, making it ideal for modern applications, while SATA is more commonly used for traditional hard drives. Understanding these interfaces helps users choose the right storage solutions for their needs.
