What is NCQ in the hard drive?

NCQ (Native command Queuing) is a technology designed to improve the performance and stability of a hard disk under increasing load. When the user's application sends multiple instructions to the user's hard drive, the NCQ hard drive can optimize the order of these instructions, thus reducing the mechanical load to achieve the goal of improving performance. NCQ technology is a kind of order to optimize the workload inside the hard disk, by reordering the commands in the internal queue to realize the intelligent data management, improve the hard drive due to the mechanical parts of the various performance constraints.

NCQ Introduction

NCQ is called the Full Speed command queue (Native command Queuing,ncq). Full-speed command queues are the most advanced and expected features of SATA II, an important part of the Sataⅱ specification and the only technology associated with the Sataⅱ specification for hard disk performance. NCQ is a powerful interface/hard disk technology that improves hard drive performance and service life by optimizing the execution order of the jobs within the hard disk.
