In computing, Native Command Queuing (NCQ) is an extension of the Serial ATA protocol allowing hard disk drives to internally optimize the order in which received read and write commands are executed.

Native command queuing (NCQ) is a technology enabling SATA hard drives to accept more than one command at a time by optimizing the order in which read and write commands are executed. This increases the performance of the drive by limiting the number of drive head movements when multiple read/write requests are queued.

Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard disks on computers. It can do this under certain situations by allowing the individual hard disk to internally optimize the order in which it executes the read and write requests it received.

NCQ (Native Command Queuing) is a technology designed to increase the performance of hard disk drives under certain situations by allowing the hard drive to change the order dynamically (according to the current workload) in which received read and write commands are executed using a particular internal buffer.
