Native Command Queuing (NCQ) is a feature supported by Advanced Host Controller Interface (AHCI). It allows ATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency. NCQ, when used in conjunction with a hard drive that supports NCQ, can increase storage performance on random workloads.
In order to take advantage of NCQ, you need:
- Intel® Rapid Storage Technology (Intel® RST)
- Hard drive(s) that supports NCQ
- Intel® Chipsets using a controller hub that supports AHCI
