What is Native Command Queuing (NCQ)?

What does NCQ stand for?

Native Command queuing (NCQ) is a technology permitting SATA difficult drives to just accept more than one command at a time via optimizing the order in which examine and write commands are achieved. This increases the overall perFormance of the drive by way of restricting the Range of pressure head actions while multiple study/write requests are Queued.

What Does Native Command Queuing Mean?

NCQ replaces tagged command queuing (TCQ), which is used with parallel ATA (PATA). The manner in which TCQ interacts with the working sySTEM (OS) taxes the CPU in go back for little overall performance advantage.

Both in the difficult pressure and within the SATA Host Bus Adapter, NCQ must be supported and enabled and the proper driver have to be loaded into the OS. Some OSs encompass the required frequent drivers (which include Windows Vista and Windows 7) whereas others require seller-precise drivers to be loaded to permit NCQ, like Windows XP.

NCQ will also be used in solid-kingdom drives (SSDs), drives containing statistics in non-unsTable Memory Chips and include no shifting Components. Here, Latency (the put off in processing instructions) is observed at the Host no longer at the power. The pressure Makes use of NCQ to make certain it has instructions to Method whilst the Host Adapter is processing CPU obligations.
