SATA connectors are a type of interface used to connect storage devices like hard drives and solid-state drives to a computer's motherboard. They allow for fast data transfer rates, making them essential for modern computing. The connectors come in different versions, such as SATA I, SATA II, and SATA III, each offering improved speeds and performance. These connectors are typically flat and have a distinctive L-shape, which helps ensure they are plugged in correctly. SATA cables are used to connect the drives to the motherboard, while power is supplied through a separate SATA power connector.
