SATA cables are used to connect storage devices, like hard drives and solid-state drives, to a computer's motherboard. They enable the transfer of data between these devices, allowing your computer to read and write information efficiently. SATA stands for Serial Advanced Technology Attachment, which describes the technology behind these cables. These cables come in different versions, such as SATA I, SATA II, and SATA III, each offering varying speeds for data transfer. The most common type today is SATA III, which can transfer data at speeds up to 6 Gbps. SATA cables are typically thin and flexible, making them easy to manage inside a computer case.
