The 6Gbps data transfer throughout makes it superior to previous technologies such as ATA and PATA. That means commands will be rescheduled and permits the host to send more commands to the hard drive as it searches data for another command. NCQ allows improved performance through the ability to augment the orders of implementation of reading/writing commands. Hot swapping refers to the ability to replace components of a computer system without having to shut down the entire system. Advanced host controller interface (AHCI) is the standard interface for SATA which supports hot swapping and native command queuing (NCQ). The SATA technology was first introduced in 2000 to replace ATA and PATA to provide faster data transfer rates and hot-swapping. There have been multiple versions of the SATA interface developed to meet the need for increased storage capacity and bandwidth. It is the most commonly used technology to connect hard drives to a PC's motherboard. Serial advanced technology attachment denoted as SATA or Serial ATA, or S-ATA is a computer bus interface mostly connecting host bus adapters to mass storage devices including hard drives.
