SATA 3Gb/s is a type of interface used to connect storage devices, such as hard drives and solid-state drives, to a computer's motherboard. The "3Gb/s" refers to the maximum data transfer rate of 3 gigabits per second, which allows for faster data access compared to older interfaces. This speed is beneficial for improving overall system performance, especially when loading applications or transferring large files. Introduced in 2009, SATA 3Gb/s is part of the SATA (Serial Advanced Technology Attachment) standard, which has evolved over time. It is commonly used in both consumer and enterprise environments, providing a reliable connection for various storage solutions.
