What is SATA Connector
SATA (Serial Advanced Technology Attachment) connector is a type of data cable used to connect hard drives, solid-state drives (SSDs), and optical drives to a computer's motherboard. It is the standard interface for most modern storage devices and supports high-speed data transfer rates. SATA connectors come in different sizes and shapes, including the 7-pin and 15-pin versions, which can transmit power in addition to data signals. SATA has largely replaced the older IDE (Integrated Drive Electronics) and SCSI (Small Computer System Interface) connectors for internal storage devices.
