Queuing
Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard disk
drives by allowing the individual hard disk to internally optimize the order in which received read and
write commands are executed. This can reduce the amount of unnecessary going back-and-forth on the
drive's heads, resulting in increased performance for workloads where multiple simultaneous read/write
requests are outstanding, most often occurring in server or storage-type applications. Without NCQ the
drive has to process and complete one command at a time. For NCQ to be enabled, it must be
supported and turned on in the controller and in the hard drive itself.
