A SATA cable is a type of connection used to link storage devices, such as hard drives and solid-state drives, to a computer's motherboard. It stands for Serial Advanced Technology Attachment and is designed to transfer data quickly and efficiently. SATA cables are commonly used in modern computers due to their speed and reliability. These cables come in different versions, with SATA III being the most widely used, offering data transfer rates of up to 6 Gbps. They are typically thin and flexible, making them easy to manage within a computer case. Proper use of SATA cables ensures optimal performance of storage devices.
