SATA cables are used to connect storage devices, like hard drives and solid-state drives, to a computer's motherboard. They allow for the transfer of data between the storage device and the computer, enabling the system to read and write information. SATA stands for Serial Advanced Technology Attachment, which refers to the technology that facilitates this connection. These cables are typically thin and flat, making them easier to manage inside a computer case compared to older IDE cables. SATA cables come in different versions, with newer ones supporting faster data transfer rates, enhancing overall system performance.
